Description (Abstract):
    A set of photometric data concerning two distant clusters of
    galaxies is presented : Cl1613+3104 (z=0.415) and Cl1600+4109
    (z=0.540). The photometric survey extends to a field of about
    4x3 arcmin. It was performed in 3 filters: Johnson B, and Thuan-Gunn
    g and r. The sample includes 679 objects in the field of Cl1613+3104
    and 335 objects in Cl1600+4109.

Note (1): coordinates with respect to the central galaxy,
          x increasing southward, y increasing westward
Note (3): limiting isophote 27.0 mag/arcsec2 in Cl1613+3104 and
          27.5 mag/arcsec2 in Cl1600+4109.
Note (4): Criterion to discriminate between stars and galaxies.
          Stars, galaxies and unclassified objects are identified 
          respectively with 0, 2 and 1.
Note (5): Final classification of objects as
          stars (0), galaxies (2) or ambiguous (1), 
          according to the results in columns 9 to 11. This is
          the criterion used in the paper by Vilchez-Gomez et al.
          (1995, A&A submitted). Saturated stars are identified by "5".
