olga.vozyakova@student.upjs.skvirtual-observatoriescatalogsThe Pavol Jozef Šafárik University Archive's TAP end point. The Table Access Protocol (TAP) lets you execute queries against our database tables, inspect various metadata, and upload your own data. It is thus the VO's premier way to access public data holdings. Tables exposed through this endpoint include: gaia_source_lite_eb, lightcurves, raw_data, ts_ssa, vari_eclipsing_binary_lite from the gaiadr3_eb schema, obscore from the ivoa schema, acepheids, blap, cepheids, cv, dsct, eclipsing, heartbeat, lightcurves, m54, miras, objects_all, raw_data, rotating, rrlyr, t2cep, transits, ts_ssa from the ogle schema, lightcurves, objects, ts_ssa from the personal schema, columns, groups, key_columns, keys, schemas, tables from the tap_schema schema, main from the upjs_img schema, lightcurves, objects, raw_data, ts_ssa from the upjs_ts schema.https://skvo.science.upjs.sk/__system__/tap/run/infoIsServiceForPavol Jozef Šafárik University Archive Obscore Tablehttps://skvo.science.upjs.sk/tapObscore-1.1ADQL2.02.1The Astronomical Data Query Language is the standard IVOA dialect of SQL; it contains a very general SELECT statement as well as some extensions for spherical geometry and higher mathematics.

gavo_getauthority(ivoid TEXT) -> TEXT

returns the authority part of an ivoid (or, more generally a URI). So, ivo://org.gavo.dc/foo/bar#baz becomes org.gavo.dc. The behaviour for anything that's not a full URI is undefined.

gavo_ipix(long REAL, lat REAL) -> BIGINT

gavo_ipix returns the q3c ipix for a long/lat pair (it simply wraps the 13c_ang2ipix function). This is probably only relevant when you play tricks with indices or PPMXL ids.

gavo_match(pattern TEXT, string TEXT) -> INTEGER

gavo_match returns 1 if the POSIX regular expression pattern matches anything in string, 0 otherwise.

gavo_mocintersect(moc1 MOC, moc2 MOC) -> MOC

returns the intersection of two MOCs.

gavo_mocunion(moc1 MOC, moc2 MOC) -> MOC

returns the union of two MOCs.

gavo_specconv(expr DOUBLE PRECISION, dest_unit TEXT) -> DOUBLE PRECISION

returns the spectral value expr converted to dest_unit. expr has to be in either energy, wavelength, or frequency, and dest_unit must be a VOUnit giving another spectral unit (e.g., MHz, keV, nm, or Angstrom). This is intended to let users express spectral constraints in their preferred unit independently of the choice of unit in the database. Examples:: gavo_specconv(obscore.em_min, "keV") > 300 gavo_specconv(obscore.em_max, "MHz") > 30 gavo_specconv(spectral_start, "Angstrom") > 4000 There is a variant of gavo_specconv accepting expr's unit in a third argument.

gavo_specconv(expr NUMERIC, expr_unit TEXT, dest_unit TEXT) -> NUMERIC

returns expr assumed to be in expr_unit expressed in dest_unit. This is a variant of the two-argument gavo_specconv for when the unit of expr is not known to the ADQL translator, either because it because it is a literal or because it does not look like a spectral unit. Examples:: gavo_specconv(656, 'nm', 'J') BETWEEN spectral_start AND spectral_end gavo_specconv(arccos(phi)*incidence, 'Hz', 'eV') Clearly, overriding known units is likely to yield bad results; the translator therefore warns if an existing unit is overridden with a different unit.

gavo_vocmatch(vocname TEXT, term TEXT, matchagainst TEXT) -> INTEGER

returns 1 if matchagainst is term or narrower in the IVOA vocabulary vocname, 0 otherwise. This is intended for semantic querying. For instance, gavo_vocmatch('datalink/core', 'calibration', semantics) would be 1 if semantics is any of calibration, bias, dark, or flat. For RDF-flavoured vocabularies (strict trees), term will expand to the entire branch rooted in term. For SKOS-flavoured vocabularies (where narrower is not transitive), only directly narrower terms will be included. Both the term and the vocabulary name must be string literals (i.e., constants). matchagainst can be any string-valued expression.

ivo_geom_transform(from_sys TEXT, to_sys TEXT, geo GEOMETRY) -> GEOMETRY

The function transforms ADQL geometries between various reference systems. geo can be a POINT, a CIRCLE, or a POLYGON, and the function will return a geometry of the same type. In the current implementation, from_sys and to_sys must be literal strings (i.e., they cannot be computed through expressions or be taken from database columns). All transforms are just simple rotations, which is only a rough approximation to the actual relationships between reference systems (in particular between FK4 and ICRS-based ones). Note that, in particular, the epoch is not changed (i.e., no proper motions are applied). We currently support the following reference frames: ICRS, FK5 (which is treated as ICRS), FK4 (for B1950. without epoch-dependent corrections), GALACTIC. Reference frame names are case-sensitive.

ivo_hashlist_has(hashlist TEXT, item TEXT) -> INTEGER

The function takes two strings; the first is a list of words not containing the hash sign (#), concatenated by hash signs, the second is a word not containing the hash sign. It returns 1 if, compared case-insensitively, the second argument is in the list of words coded in the first argument. The behaviour in case the the second argument contains a hash sign is unspecified.

ivo_hasword(haystack TEXT, needle TEXT) -> INTEGER

gavo_hasword returns 1 if needle shows up in haystack, 0 otherwise. This is for "google-like"-searches in text-like fields. In word, you can actually employ a fairly complex query language; see https://www.postgresql.org/docs/current/textsearch.html for details.

ivo_healpix_center(hpxOrder INTEGER, hpxIndex BIGINT) -> POINT

returns a POINT corresponding to the center of the healpix with the given index at the given order.

ivo_healpix_index(order INTEGER, ra DOUBLE PRECISION, dec DOUBLE PRECISION) -> BIGINT

Returns the index of the (nest) healpix with order containing the spherical point (ra, dec). An alternative, 2-argument form ivo_healpix_index(order INTEGER, p POINT) -> BIGINT is also available.

ivo_histogram(val REAL, lower REAL, upper REAL, nbins INTEGER) -> INTEGER[]

The aggregate function returns a histogram of val with nbins+2 elements. Assuming 0-based arrays, result[0] contains the number of underflows (i.e., val<lower), result[nbins+1] the number of overflows. Elements 1..nbins are the counts in nbins bins of width (upper-lower)/nbins. Clients will have to convert back to physical units using some external communication, there currently is no (meta-) data as lower and upper in the TAP response.

ivo_interval_has(val NUMERIC, iv INTERVAL) -> INTEGER

The function returns 1 if the interval iv contains val, 0 otherwise. The lower limit is always included in iv, behaviour on the upper limit is column-specific.

ivo_interval_overlaps(l1 NUMERIC, h1 NUMERIC, l2 NUMERIC, h2 NUMERIC) -> INTEGER

The function returns 1 if the interval [l1...h1] overlaps with the interval [l2...h2]. For the purposes of this function, the case l1=h2 or l2=h1 is treated as overlap. The function returns 0 for non-overlapping intervals.

ivo_nocasematch(value TEXT, pattern TEXT) -> INTEGER

ivo_nocasematch returns 1 if pattern matches value, 0 otherwise. pattern is defined as for the SQL LIKE operator, but the match is performed case-insensitively. This function in effect provides a surrogate for the ILIKE SQL operator that is missing from ADQL. On this site, this is actually implemented using python's and SQL's LOWER, so for everything except ASCII, your mileage will vary.

ivo_normal_random(mu REAL, sigma REAL) -> REAL

The function returns a random number drawn from a normal distribution with mean mu and width sigma. Implementation note: Right now, the Gaussian is approximated by summing up and scaling ten calls to random. This, hence, is not very precise or fast. It might work for some use cases, and we will provide a better implementation if this proves inadequate.

ivo_simbadpoint(identifier TEXT) -> POINT

gavo_simbadpoint queries simbad for an identifier and returns the corresponding point. Note that identifier can only be a literal, i.e., as simple string rather than a column name. This is because our database cannot query simbad, and we probably wouldn't want to fire off millions of simbad queries anyway; use simbad's own TAP service for this kind of application.

ivo_string_agg(expression TEXT, delimiter TEXT) -> TEXT

An aggregate function returning all values of expression within a GROUP contcatenated with delimiter

ivo_to_jd(d TIMESTAMP) -> DOUBLE PRECISION

The function converts a postgres timestamp to julian date. This is naive; no corrections for timezones, let alone time scales or the like are done; you can thus not expect this to be good to second-precision unless you are careful in the construction of the timestamp.

ivo_to_mjd(d TIMESTAMP) -> DOUBLE PRECISION

The function converts a postgres timestamp to modified julian date. This is naive; no corrections for timezones, let alone time scales or the like are done; you can thus not expect this to be good to second-precision unless you are careful in the construction of the timestamp.

TABLESAMPLE

Written after a table reference, TABLESAMPLE(10) will make the database only use 10% of the rows; these are `somewhat random' in that the system will use random blocks. This should be good enough when just testing queries (and much better than using TOP n).

MOC

A geometry function creating MOCs. It either takes a string argument with an ASCII MOC ('4/13 17-18 8/3002'), or an order and another geometry.

Most of the observations are carried out in the Cousins *I* filter, with auxiliary measurements in the *V* filter. High-cadence, long-term observations of crowded fields have led to the systematic discovery and classification of variable stars. The OGLE Collection of Variable Stars (OCVS) contains over one million objects. OCVS light curves span three survey phases: OGLE-II (1996-2000), OGLE-III (2001-2009), and OGLE-IV (2010-present). The VO-compliant re-publication of the OCVS light curve collection allows bulk download for objects with a specific variability class and parameters, which can be very handy for ML-based light curve analysis and related applications. The original data of the republished collection can be found at: https://www.astrouw.edu.pl/ogle/ogle4/OCVS/ While republishing, we almost preserve the original data structure. That is, there are tables with variable star parameters split by variability type (Cepheids, Eclipsing and Ellipsoidal Binaries, RR Lyrae stars, etc.) and by sky field: Galactic Bulge (BLG), Magellanic Clouds (LMC, SMC), Galactic Disc (GD). A few tables are related only to a variability class (e.g., Cataclysmic Variables - CV, BLAPs, Anomalous Cepheids in the Milky Way - ACEP/GAL) or a specific field (M54 variables, which comprise diverse classes). All observed objects with their main parameters are aggregated in the object_all table, which facilitates generic queries across all classes. This table is served by Cone Search. The ts_ssa table is the main table for light-curve queries. It is served by TAP and SSA services. The time series themselves, as well as previews of folded and unfolded light curves, can be accessed via DataLink from the ts_ssa and ObsCore tables. Direct links to previews of folded curves are placed in the *preview* column of both the *ts_ssa* and *ObsCore* tables.ogle.ts_ssa This table contains metadata about the OCVS photometric time series in IVOA SSA format. The actual data is available through a datalink service.

Different times are defined for each band. For G, it is the field-of-view transit averaged observation time. For BP and RP, it is the observation time of the BP CCD transit. The units are Barycentric JD (in TCB) in days -2,455,197.5, computed as follows. First the observation time is converted from On-board Mission Time (OBMT) into Julian date in TCB (Temps Coordonnee Barycentrique). Next a correction is applied for the light-travel time to the Solar system barycentre, resulting in Barycentric Julian Date (BJD). Finally, an offset of 2,455,197.5 days is applied (corresponding to a reference time $T_0$ at 2010-01-01T00:00:00) to have a conveniently small numerical value. Although the centroiding time accuracy of the individual CCD observations is (much) below 1~ms (e.g. in BP and RP), the G band observation time is averaged over typically 9 CCD observations taken in a time range of about 44sec.dtime.epochdoubleindexedfluxBand flux value for the transit.

The observations were carried out to monitor selected fields centred on eclipsing binary stars with two small telescopes. The first instrument, ZIGA (PlaneWave CDK20, Corrected Dall–Kirkham), has a 508 mm aperture and is equipped with a Moravian Instruments G4-16000 CCD camera with UBVRI Bessell photometric filters. The second instrument, Alica (Explore Scientific MN-152, Maksutov–Newton), has a 152 mm aperture and is equipped with a Moravian Instruments G2-8300 CCD camera with Sloan g′ r′ i′ photometric filters. Both telescopes are currently in operation at the observatory. The time series were produced with a custom photometric pipeline (Parimicha, Š., in preparation). Differential photometry is performed using comparison star magnitudes from APASS DR9. Beyond the primary target (typically an eclipsing binary), the pipeline derives calibrated magnitudes for all stars in the field with sufficient signal-to-noise ratio. This approach, we believe, may help researchers follow the behaviour of other interesting objects over time. For each photometric point, we provide the list of comparison stars used in its calculation (which may vary for each star and each image). The corresponding calibrated images are published separately in the upjs_img image collection.upjs_ts.ts_ssa This table contains metadata about the photometric timeseries from Kolonica in IVOA SSA format.

The Kolonica Observatory is located on the Kolonica Saddle and is operated by the Vihorlat Observatory in Humenné. It lies in the northeastern part of Slovakia, within the Poloniny Dark-Sky Park, a location with the darkest night skies in Slovakia and among the darkest in Europe. Two small telescopes were used to obtain the images in this collection. The first telescope, named ZIGA (PlaneWave CDK20 — Corrected Dall–Kirkham), has a 508 mm aperture and is equipped with a Moravian Instruments G4-16000 CCD camera and UBVRI Bessell photometric filters. The second telescope, named Alica (Explore Scientific MN-152 — Maksutov–Newton), has a 152 mm aperture and is equipped with a Moravian Instruments G2-8300 CCD camera and g′ r′ i′ Sloan photometric filters. Both telescopes are currently in operation, and the archive is expected to be updated with new data. We publish the photometric time series derived from these images in the upjs_ts collection.upjs_img.main The images in this collection were acquired to monitor selected sky fields around eclipsing binary stars at the Kolonica Observatory, Slovakia.
