Beginning of ReadMe : J/AJ/146/139 2010 photometry of variable stars from Dome A (Wang+, 2013) ================================================================================ Photometry of variable stars from Dome A, Antarctica: results from the 2010 observing season.

We carried out high-cadence time-series aperture photometry of 9125 stars with i< 15.3mag located in a 23deg^2^ region centered on the south celestial pole. We identified 188 variable stars, including 67 new objects relative to our 2008 observations, thanks to broader synoptic coverage, a deeper magnitude limit, and a larger field of view. We used the photometric data set to derive site statistics from Dome A. Based on two years of observations, we find that extinction due to clouds at this site is less than 0.1 and 0.4mag during 45% and 75% of the dark time, respectively. Description: The region surrounding Dome A (elevation: 4093m above mean sea level) in the Antarctic plateau is likely the best astronomical site on Earth. We developed an observatory capable of year-round operations called PLATO, and a quad-telescope called CSTAR (the Chinese Small Telescope ARray). The observatory is part of the Chinese Kunlun station, located at Dome A. Observations were carried out using CSTAR (unit#3), which we described in detail in Wang et al. (2011, cat. J/AJ/142/155). Briefly, it is a Schmidt-Cassegrain wide-field telescope with a pupil entrance aperture of 145mm, a Sloan i-band filter, and a 1K*1K frame-transfer CCD with a plate scale of 15.7"/pixel, giving a field of view 4.5deg on a side. Scientifically useful images were acquired from 2010 March 29 to 2010 September 27 (Antarctic winter season).
