| VAR_EXP_ID | twoxmm, twoxmm_v1_2, twoxmmi_dr3_v1_0 | XMM | If the source is detected as variable (that is, if VAR_FLAG is set to True), the exposure ID ('S' or 'U' followed by a three-digit number) of the exposure with the smallest Chi² probability is given here. | varchar | 4 | |||
| VAR_EXP_ID | xmm3dr4 | XMM | If the source is detected as variable (that is, if VAR_FLAG is set to True), the exposure ID ('S' or 'U' followed by a three-digit number) of the exposure with the smallest Chi² probability is given here. | varchar | 50 | |||
| VAR_FLAG | twoxmm, twoxmm_v1_2, twoxmmi_dr3_v1_0 | XMM | The flag is set to True if this source was detected as variable (Chi² probability < 1E-5, see PN_CHI2PROB, M1_CHI2PROB, M2_CHI2PROB) in at least one exposure. | varchar | 5 | |||
| VAR_FLAG | xmm3dr4 | XMM | The flag is set to 1 if this source was detected as variable (Chi² probability < 1E-5, see PN_CHI2PROB, M1_CHI2PROB, M2_CHI2PROB) in at least one exposure. | bit | 1 | |||
| var_flg | allwise_sc | WISE | Variability flag. The variability flag is a four-character string, one character per band, in which the value for each band is related to the probability that the source flux measured on the individual WISE exposures was not constant with time. The probability calculation uses the standard deviation of the single exposure flux measurements, w?sigp1, as well as the band-to-band flux correlation significance, q12,q23,q34. CAUTION: Estimation of flux variability is unreliable for sources that are extended (ext_flg>0), and sources whose measurements are contaminated by image artifacts in a band (cc_flags[b] != '0'). | varchar | 4 | |||
| The probability is computed for a band only when there are at least six single-exposure measurements available that satisfy minimum quality criteria. A value of "n" in a band indicates insufficient or inadequate data to make a determination of possible variability. Values of "0" through "9" indicate increasing probabilities of variation. Values of "0" through "5" are most likely not variables. Sources with values of "6" and "7" are likely flux variables, but are the most susceptible to false-positive variability. Var_flg values greater than "7" have the highest probability of being true flux variables in a band. | ||||||||
