VizieR Online Data Catalog: RR Lyrae cand. in the Galactic Center (Contreras Ramos+, 2018)
Abstract
The VISTA Variables in the Via Lactea (VVV) survey has been acquiring data since early 2010 using the VISTA InfraRed Camera (VIRCAM) mounted on the VISTA telescope in Cerro Paranal Observatory, Chile. The entire VVV observations comprise 348 tiles, 194 tiles in the bulge and 152 in the disk area, each covering a field of view (FoV) of ~1.6deg2. In this work we focus on the innermost region of the Galaxy, where the crowding is so severe that PSF modeling is mandatory.
The final catalog presented here includes 960 RRab candidate variable stars within 100 arcmin of the Galactic Center, some of which have been previously discovered (Soszynski+ 2014, J/AcA/64/177 ; Minniti+ 2016ApJ...830L..14M). (2 data files).- Publication:
