| Abstract | The VVV survey observations are carried out using the 4-metre VISTA telescope located on Cerro Paranal (Emerson et al., 2004), which, coupled with the highsensitivity infrared camera VIRCAM, has the capacity to overcome the heavy extinction of the Galactic Plane in order to reach Bulge stars up to a limiting mag nitude of Ks ~ 18 mag, with a median seeing of ~ 0.9 arcseconds. Furthermore, the high efficiency of VISTA allowed us to complete a set of single-epoch, multiband observations of the entire Bulge region of ~ 320 square degrees using Z, Y, J, H and Ks filters within less than two Bulge observing seasons. Figure 1 shows the distribution of tile images across the Bulge area covered. Each tile is the result of six exposures (known as pawprints) used to cover a field of 1.48 by 1.18 degrees in size (Arnaboldi et al., 2007). The Bulge survey area consists of 196 of these tiles distributed as shown in Figure 1. Descriptions of the observing strategy, survey goals and first results are available from Minniti et al. (2010) and Saito et al. (2010). The first data release article, DR1 (Saito et al., 2012), describes the survey products in detail. |
