This table is a unified catalogue of objects from the OGLE Collection of Variable Stars (OCVS) (https://www.astrouw.edu.pl/ogle/ogle4/OCVS).
It was constructed by merging variable-type–specific ident.dat tables with selected columns from tables containing parameters: cep.dat, cepF.dat, cep1O.dat, cepF1O.dat, cep1O2O.dat, cep1O2O3O.dat, cep2O3O.dat, Miras.dat, and others.

The corresponding light curves can be discovered via TAP through the ts_ssa or obscore tables, or through the SSA service. Light curves can be extracted using the associated DataLink services.

The **Optical Gravitational Lensing Experiment (OGLE)** is a long-term photometric 
survey operated by the University of Warsaw at Las Campanas Observatory.
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.</description><table><name>ogle.objects_all</name><title>Unified table of Variable Star Parameters from OCVS</title><description>
