======================================================================== One Thousand New Dwarf Novae from the OGLE Survey P. Mroz, A. Udalski, R. Poleski, P. Pietrukowicz M.K. Szymanski, I. Soszynski, L. Wyrzykowski, K. Ulaczyk, S. Kozlowski, and J. Skowron ======================================================================== pmroz@astrouw.edu.pl This directory contains the sample of dwarf nova candidates detected in the OGLE fields toward the Galactic bulge and the Magellanic System. The directory structure is as follows: README - this file tab1.dat - electronic version of Table 1: basic parameters of OGLE DN candidates: equatorial coordinates, OGLE database identifiers, peak magnitude, amplitude of outbursts, outburst frequency, and mean outburst duration tab2.dat - electronic version of Table 2: photometric data on the WZ Sge type candidates orb_periods.dat - list of measured orbital periods sh_periods.dat - list of measured superhump periods cv_xrays.dat - list of X-ray counterparts to dwarf novae cv_vsx.dat - list of cross-identifications with the International Variable Star Index databse (Watson 2006) cv_K2C9.lis - list of dwarf novae within the K2 Campaign 9 superstamp (version of October 1st, 2016) phot.tar.gz - gzipped I-band photometry of individual objects fcharts.tar.gz - gzipped finding charts for individual objects Finding charts are png images. These are 60"x60" subframes of the I-band reference frames centered on the star. 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 source should include the appropriate reference(s) to OGLE paper(s).
