              in OGLE-I data (including those from first edition of
              the catalog of OGLE-I variable stars). See below for details

Catalog data table contains following data. Stars are sorted by period.

Column Description

  1   OGLE-I field name
  2   Star no. in the OGLE-I database
  3   R.A. (J2000)
  4   Dec. (J2000)
  5   calibrated I mag
  6   calibrated V-I color (9.99 if no data in V available for a star;
      I magnitude for these stars was calibrated with typical value of V-I=1.0)
  7   period in days
  8   type classification


REMARK: Two stars survived all checks and entered the catalog twice,
with two different period values:

BW11 72188 (EWa)
BW7 66654  (EWs)
