This directory contains OGLE-III photometric maps of 267 Galactic bulge
fields (BLG100-BLG366) observed during the OGLE-III phase of the OGLE survey. 

The directory structure is as follows:

where
  DB_no - number in the database,
  RA, DEC - equatorial coordinates,
  X_ref,Y_ref - pixel coordinates in the I-band reference image,
  V, V-I, I - photometry data,
  Ng - number of "good" measurements,
  Nb - number of "bad" (removed with 5 sigma rejection alghoritm) measurements,
  sig - standard deviation of "good" measurements.

WARNING!!! "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).
