This directory contains the catalog of variable stars in the Gaia South
Ecliptic Pole field.
The directory structure is as follows:
README - this file
list.dat - list of variable stars with their parameters
remarks.txt - remarks on selected objects
phot/I/ - I-band photometry of individual objects
phot/V/ - V-band photometry of individual objects
phot.tar.gz - gzipped phot/ directory
fcharts/ - finding charts of individual objects
ogle-sep-varstars.fits - FITS table version version of the list.dat file

Finding charts are gzipped PostScript images. These are 60"x60" subframes
of the I-band reference frames centered on the star. White cross marks the
star. North is up and East to the left.
Any presentation of the scientific analysis or usage of the data from this
catalog should include the appropriate reference(s) to OGLE paper(s).
