| RA | twoxmm | XMM | Corrected Right Ascension of the detection in degrees (J2000) after statistical correlation of the emldetect coordinates, RA_UNC and DEC_UNC, with the USNO B1.0 optical source catalogue using the SAS task eposcorr. In case where the cross-correlation is determined to be unreliable no correction is applied and this value is therefore the same as RA_UNC. | float | 8 | degrees | ||

| Celestial Right Ascension as computed in the processing pipeline, accurate to of order 0.1 arcsec. Note that original catalogue data has only r*4 storage precision, accurate only to ≈ 50mas. RA and Dec in the database are derived more precisely from WCS in the header and x and y attributes. | ||||||||

| ra | dxsVariability, udsVariability | WSA | Mean Right Ascension | float | 8 | Degrees | POS_EQ_RA_MAIN | |
| The Variability table contains statistics from the set of observations of each source. At present, the mean ra and dec and the error in two tangential directions are calculated. The "ra" direction is defined as tangential to both the radial direction and the cartesian z-axis and the "dec" direction is defined as both the radial direction and the "ra" direction. Since the current model is just the mean and standard deviation of the data, then the chi-squared of the fit=1. Data from good frames across all bands go into the astrometric model determination. This will include bands in non-synoptic filters: the one observation in these bands can help. In future releases a fit will be made to the rms data as a function of magnitude in each band, as has already happened for photometric data and a motion model that incorporates proper motion (and possibly parallax) will be used. The motion model is a parameter in the VarFrameSetInfo table. | ||||||||
