The All Sky Automated Survey. The Catalog of Variable Stars. II. 0h-6h Quarter of the Southern Hemisphere

This paper describes the first part of the photometric data from the 9°×9° ASAS camera monitoring the whole southern hemisphere in the V-band. Data acquisition and reduction pipeline are described and preliminary list of variable stars presented. Over 1 300 000 stars brighter than V=15 mag on 10 000 frames were analyzed and 3126 were found to be variable (1055 eclipsing, 770 regularly pulsating, 132 Mira and 1169 other, mostly SR, IR and LPV stars). Periodic light curves have been classified using the fully automated algorithm, which is described in detail. Basic photometric properties are presented in the tables and exemplary light curves are printed for reference. All photometric data are available over the Internet at http://www.astrouw.edu.pl/~gp/asas/asas.html or http://archive.princeton.edu/~asas.
