Table information for 'gaia.dr2_ts_ssa'

General

Table Description: This table contains about 1.5 Million photometric timeseries for roughly 0.5 Million objects. Photometry is available in the Gaia G, BP, and RP bands for epochs between 2014-07-25 and 2016-05-25. The spectra are available in VOTable format with the timeseries annotation proposed in the Nadvornik et al IVOA note.

This table is available for ADQL queries and through the TAP endpoint.

Resource Description:

At the GAVO data Center, we hold several data collections part of or derived from Gaia data release 2:
