cds-question@unistra.frvariable-starseclipsing-binary-starsconstellationsphotometryvisible-astronomyThe Berlin Exoplanet Search Telescope II (BEST II) is a ground-based, small aperture, wide-angle telescope used to search for stellar light variations in the southern hemisphere. We report the results of a monitoring campaign observing a field in the Puppis constellation in late 2011/early 2012. Light curves were obtained for 130472 stars, out of which we identify 2169 variables, including 1829 newly discovered, 26 previously known, and 314 suspected variable stars. We determine periods and variability class for two previously known, but only suspected to be, variable stars. For eight individual eclipsing binary stars, including the two previously known but unclassified binaries, the system parameters were derived at the epoch of the observation by modeling the light curves. Eventually, in a catalog for all variable stars, we present coordinates, magnitude, and elements of light variations, e.g., epoch, period, amplitude, type, and light curves. This catalog concludes the BEST/BEST II project.2018AJ....156..204Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/156/204CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/gcvs : General Catalogue of Variable Stars (Samus+, 2007-2017)J/AJ/134/766 : BEST variable stars in LRc1 field (Karoff+, 2007)J/AJ/134/1560 : BEST periodic variable stars in IR01 field (Kabath+, 2007)J/AJ/136/654 : BEST periodic variable stars in LRa1 field (Kabath+, 2008)J/A+A/506/569 : BEST-II periodic variables in CoRoT LRa02 field (Kabath+, 2009)J/AJ/137/3911 : BEST periodic variable stars in LRc2 field (Kabath+, 2009)J/AJ/143/140 : BEST-II periodic variables in CoRoT LRa02 field.
