ANDICAM J(max) − J(min) is the difference between the maximum and minimum ANDICAM J magnitudes. ANDICAM 〈J〉 − 2MASS J is the difference between the average ANDICAM J and the 2MASS J magnitudes. ANDICAM I(max) − I(min) is the difference between the maximum and minimum ANDICAM I magnitudes. ANDICAM 〈I〉 − DENIS I is the difference between the average ANDICAM I and the DENIS I magnitudes. fl_corr = 1 if the Pearson correlation coefficient of the simultaneously taken I- and J-magnitude vectors is larger than 0.5. fl_var = 1 if the standard deviation of the I-magnitude vector exceeds twice that of field stars at similar magnitudes or if the standard deviation of the J-magnitude vector exceeds twice that of other bright field stars (non-variable calibrators). Period of the periodic light variation detected in the Lomb–Scargle periodogram (see text). FAP is the false alarm probability corresponding to the power level of the adopted period. ΔI/2 is the semi-amplitude of the photometric I-band light curve.
