CLASSX_CLASS (String): Classification of the X-ray source as described in Section 3.9 of the users guide. The classifications in 5XMM are AGN, stars, Galactic X-ray binaries, cataclysmic variables, background AGN, extra-galactic X-ray binary and extended sources.
CLASSX_OUTLIER (Double): The outlier measure (maximum 10) which indicates the likelihood that a source does not fit one of the 5XMM classifications i.e. AGN, stars, Galactic X-ray binaries, cataclysmic variables, background AGN, extra-galactic X-ray binary and extended sources, see Section 3.9 of the users guide. The higher the value, the more likely none of the classes are adapted to the source nature.
CLASSX_PROB_AGN, CLASSX_PROB_STAR, CLASSX_PROB_GAL_XRB, CLASSX_PROB_GAL_CV, CLASSX_PROB_BKG_AGN, CLASSX_PROB_EXTRAGAL_XRB, CLASSX_PROB_EXTENDED (Double) [posterior probability]: The posterior probability resulting from the X-ray source classification which indicates the probability that a source is best described by one of the 5XMM classifications i.e. AGN, stars, Galactic X-ray binaries, cataclysmic variables, background AGN, extra-galactic X-ray binary and extended sources, see Section 3.9 of the users guide. The closer to unity, the more the class describes the source nature.

OM_b_AB_MAG, OM_b_AB_MAG_ERR (Double) [magnitude, err]: Magnitude measure of the OM source in one of the 6 OM filters (where b = UVW2 / UVM1 / UVW1 / U / B / V) using the AB system and the associated error for each filter, as described in the User Guide (Section 3.7).

OM_b_EXTENDED_FLAG (Integer): Measure of the extent of the OM source in one of the 6 OM filters (where b = UVW2 / UVM1 / UVW1 / U / B / V), see the User Guide (Section 3.7). 0 implies point-like and 1 implies extended.
OM_b_CHISQ, OM_b_CHISQ_DOF (Double): Measure of the long-term variability of the OM source in one of the 6 OM filters (where b = UVW2 / UVM1 / UVW1 / U / B / V), where a source has been detected in multiple XMM-Newton observations in the same XMM-OM passband and a χ² value is computed for the sequence of magnitude measurements compared to a single, constant magnitude. The corresponding degrees of freedom is one less than the number of measurements in that band. The χ² divided by the degrees of freedom can be used as an indicator as to whether there is evidence for variability between observations in that XMM-OM passband. Where variability is suggested by the χ², the individual measurements can be consulted in XMM-SUSS v.6.2, see the User Guide (Section 3.7).
