Notes. The Col. 1 presents the class of variability. The Col. 3 displays the number of variable stars obtained from the OGLE catalogs. The Col. 4 lists stars without time series in the I-band filter. The Col. 5 indicates stars with fewer than 60 observations. The Col. 6 shows stars that are observed in both OGLE III and OGLE IV. The Col. 7 shows stars eliminated due to an internal match within 1 arcsec. The Col. 8 presents the final count of independent stars. Table A.1 shows the OGLE reference for each variability class.
