Coordinates, raw magnitudes, and time information (applause_dr1.raw_lightcurve)

Description

This table contains magnitudes raw magnitudes (from source table), sky coordinates and source designations from the source_calib table, and observation time from the exposure table. Each row in the table has a unique source_id, which is the same as in the source and source_calib tables. It's a convenience for constructing a lightcurve for a selected object. It does not provide periods etc. Unique Identifier source_id
