This directory contains details on magnetic stars (alpha2 CVn type,
ACV) identified in the OGLE-III Galactic bulge (BLG) fields and
recently confirmed spectroscopically.

The directory structure is as follows:

Finding charts are gzipped Postscript images. The names of the files are
in the form: OGLE-BLG-ACV-NNN.ps.gz. The finding charts 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 the
OGLE catalog of variable stars should include appropriate references
to OGLE papers.
