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 |

The following are for a standard set of time series statistics performed on the TAMMAG2 magnitude. For more information on SuperWASP time series statistics, refer to the documentation.
