2MASS vs. our DaoPHOT photometry in tiles “d003” (left panels) and “b305” (right panels). The backgrounds show source number density. The green curves show moving medians with a box width of 0.2 mag while the red horizontal lines mark the zero difference value between the 2MASS and our DaoPHOT catalogs. The blue vertical lines show the magnitude limits of (J, H, Ks) = (13.8, 12.8, 12.8) mag and (13.0, 11.8, 11.8) mag for VVV disk tiles and bulge tiles, individually. The source brighter than above limits have been replaced by 2MASS photometric results.
