"Magic" numbers: 99.999 for magnitude and 9.999 for color and standard deviation denote "no measurement". A plus (+) sign in the N_b V-band column indicates that the V-band counterpart of an object was found in more than one subfield and the photometry was merged. Please NOTE: Any presentation of the scientific analysis or usage of the data from the OGLE-III VI maps of the Galactic bulge should cite the apropriate OGLE paper(s).
