Ratajczak ======================================================================= piwanek@astrouw.edu.pl This directory contains the OGLE collection of rotating variables discovered toward the Galactic bulge. The directory is structured as follows: README - this file ident.dat - identification of stars rot.dat - parameters of rotating variables phot_ogle2/I/ - I-band OGLE-II photometry of individual stars (1997-2000) phot_ogle2/V/ - V-band OGLE-II photometry of individual stars (1997-2000) phot_ogle2.tar.gz - gzipped phot_ogle2/ directory phot_ogle3/I/ - I-band OGLE-III photometry of individual stars (2001-2009) phot_ogle3/V/ - V-band OGLE-III photometry of individual stars (2001-2009) phot_ogle3.tar.gz - gzipped phot_ogle3/ directory phot_ogle4/I/ - I-band OGLE-IV photometry of individual stars (2010-2024) phot_ogle4/V/ - V-band OGLE-IV photometry of individual stars (2010-2024) phot_ogle4.tar.gz - gzipped phot_ogle4/ directory fcharts/ - finding charts of individual stars remarks.txt - remarks on selected objects paper.pdf - PDF version of the paper Iwanek et al.

The names of the files are in the form: OGLE-BLG-ROT-NNNNNN.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 collection of rotating variables should include the appropriate reference(s) to OGLE paper(s).
