 Variable stars are selected via two methods: their periodicity (via
the Lomb-Scargle periodogram) and their general variability (via
the Stetson variability index). We identified variable stars using 3
criteria:
(i) an automated Stetson selection;
(ii) a periodic selection using the Lomb-Scargle periodogram;
and
(iii) a manual selection of light curves with high Stetson indices
but with one or more photometric error flags in each band.
Each of these selections is elaborated upon in the following subsec-
tions. We have detected 244 variable objects out of 658 analyzed
targets.
