Information on Service 'OGLE timeseries previews'

A service returning PNG thumbnails for time series. It takes the obs id for which to generate a preview.

For a list of all services and tables belonging to this service's resource, see Information on resource 'OGLE Time series'

Service Documentation

The original OCVS data are provided as a set of tables with stellar parameters, split by variable-star class and sky field. Indeed, different variability classes have different sets of parameters. We preserve the division by variability class, but aggregate stars of a given class from all fields into unified tables with corresponding names, such as cepheids for Classical Cepheids or eclipsing for Eclipsing Binaries and so on. This allows more precise, variability-class–specific queries.

All observed objects, together with their basic parameters, are aggregated in the object_all table, which facilitates generic queries across all classes. This table is served via 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.

ADQL Query Examples

Download all RR Lyrae light curves with period in [0.5–0.7 days] range in the I band:

SELECT ssa_targname, accref, o.period FROM ogle.ts_ssa AS t JOIN ogle.rrlyr AS o
ON t.ssa_targname = o.object_id
WHERE o.period BETWEEN 0.5 AND 0.7 AND t.ssa_bandpass = 'I'

Download all previews of the light curves with epochs (time of maximum brightness) in the future:

SELECT * from ogle.objects_all WHERE epoch > ivo_to_mjd('2027-01-01')

Find all stars with periods longer than the duration of observations in I filter:

SELECT o.* FROM ogle.objects_all o JOIN ogle.ts_ssa t ON o.object_id = t.ssa_targname
AND t.ssa_bandpass='I' WHERE o.period > ssa_timeext

Select ten eclipsing binary systems, classified as "Contact" with the longest periods:

SELECT TOP 10 accref, preview, o.* FROM ogle.eclipsing o JOIN ogle.ts_ssa t ON o.object_id = t.ssa_targname
WHERE subtype='C' and ssa_length>100 ORDER BY o.period DESC
