This directory contains:

README      - this file
P.all       - table with catalog data for variables with nearly sinusoidal
              light curves which were classified as pulsating stars.
              See below for catalog format details.
fcharts/    - subdirectory with finding charts of variables from P.all:
              FIELD_STARNO.fts.gz and FIELD_STARNO.ps.gz files contain
              60"x60" subframe centered on the star in FITS and Postscript
              format, respectively (gzipped)
phot/       - subdirectory with photometry of variables from P.all:
              FIELD_STARNO_I.dat file contains calibrated photometry
              (Julian Date, magnitude and its error) in I filter.

Catalog data table contains following data.
