Description:
File table1 contains various identifications the master list of 977
stars that were included in the photometric variability survey, and
which were cross-identified with stars in the study of Fan et al.
(1996, Cat. <J/AJ/112/628>).
Another 13 stars included in the study, but not cross-identified with
the study of Fan et al. can be found in Table 2, which is published in
the paper. These 977 stars are those that were included in a roughly
square region, 23 arcminutes on each side, centered approximately 5
arcminutes north of the cluster center. The stars have magnitudes in
the approximate range 12.5<B<18.5, 12.5<V<18.5, and 12<I<18.
File table3 contains BVI photometry for all 990 stars (from Tables 1
and 2) included in the photometric variability study.

the numbering scheme of Fan et al. (1996, Cat. <J/AJ/112/628>). Also
includes the 13 sources from Table 2, which are identified with
letters A-M.
Note (2): Values reported are in either the Cousins I or Gunn i passbands.
If n_Imag = 1, then the value is Gunn i.
