Data Columns in the SuperWASP Time Series Table
The NASA Exoplanet Archive provides access to the public SuperWASP light curves from Data Release One. See the SuperWASP page for more information on the SuperWASP data products available at the NASA Exoplanet Archive.The following table lists all of the data columns in the SuperWASP Time Series table (superwasptimeseries) that can be returned through the Exoplanet Archive's Table Access Protocol (TAP) service and Application Programming Interface (API). Please note that API support will be retiring, so we recommend using TAP for new queries.
If you have questions about the structure or use of this table in the archive format, submit a Helpdesk ticket.

Target Labels and Flags
| Database Column Name | Table Label | Description |
|---|---|---|
| sourceid | Source ID | SuperWASP Object ID |
| ra | RA [decimal degrees] | Right Ascension of the target in decimal degrees |
| dec | Dec [decimal degrees] | Declination of the target in decimal degrees |
| hjdstart | Start HJD_UTC [days] | Date of first point in light curve. The time system is the number of days since a Heliocentric Julian Date relative to the reference HJD_UTC. |
| hjdstop | End HJD_UTC [days] | Date of last point in light curve. The time system is the number of days since a Heliocentric Julian Date relative to the reference HJD_UTC. |
| hjd_ref | Reference HJD_UTC [days] | Reference HJD_UTC for the hjdstart and end_time database entries. |
| obsstart | Calendar Start Time | Calendar Date time-stamp of first point in light curve. |
| obsstop | Calendar End Time | Calendar Date time-stamp of last point in light curve. |
| tstart | Start Time | Time in seconds of the first point in light curve since the reference HJD_UTC. |
| tstop | Stop Time | Time in seconds of the last point in light curve since the reference HJD_UTC. |
| wasp_mag | WASP-band [mag] | Apparent magnitude of the target in the WASP bandpass - CCD White light in first year, and a broadband 400-700 nm filter thereafter. |
| npts | Points in Light Curve | Number of data points in light curve. Must be at least one. |
| tile | Survey Tile | Subdivision of DR1 targets for survey processing |
