VizieR Online Data Catalog: VVV Survey RR Lyr stars in Southern Galactic plane (Minniti+, 2017)
Abstract
The NIR VISTA Variables in the Via Lactea (VVV) Survey observations were acquired with the VIRCAM camera at the VISTA 4.1m telescope at ESO Paranal Observatory. In the disk fields typically 70 epochs of observations were acquired in the Ks-band between the years 2010 and 2015, in addition to complementary single-epoch observations in the ZYJH bands. The 16 NIR detectors of VIRCAM produce an image of 11.6'*11.6' and a pixel scale of 0.34''/pixel. The deep multi-epoch Ks band photometry allows us to unveil faint variable sources deep in the disk regions of our Galaxy. A search for RRab stars was made throughout tiles d001 to d038 of the VVV survey's disk field, which is a thin slice through the Galactic plane spanning 295<l<350°, and -2.24°<b<-1.05°. The total area covered is nearly 57 sq. deg, and the limiting magnitude in the specified tiles spans 17.5 to 18.5mag in the Ks-band.
