Spatial distribution of targets with optical variability statistics matched with our source catalog within 1″. Left: targets from Gaia, where blue, orange, and red colors indicate targets without classification, with best_class_score <  0.5, and best_class_score ≥ 0.5, respectively. Middle: targets from NSC, where violet, blue, cyan, green, orange, and red colors indicate the targets in u, g, r, i, z, and Y bands, respectively. Right: targets from OGLE, where blue, green, orange, and red colors indicate the targets classified as Ecls, T2Ceps, CCeps, and LPVs, respectively.
