VVV DR1: The first data release of the Milky Way bulge and southern plane from the near-infrared ESO public survey VISTA variables in the Via Lactea

The ESO public survey VISTA variables in the Via Lactea (VVV) started in 2010. VVV targets 562 square degree in the Galactic bulge and an adjacent plane region and is expected to run for about five years. This study aims to describe the progress of the survey observations in the first observing seas...

Zusammenfassung:The ESO public survey VISTA variables in the Via Lactea (VVV) started in 2010. VVV targets 562 square degree in the Galactic bulge and an adjacent plane region and is expected to run for about five years. This study aims to describe the progress of the survey observations in the first observing season, the observing strategy, and quality of the data obtained. The observations are carried out on the 4-m VISTA telescope in the ZYJHKs filters. The VVV Survey data products offer a unique dataset to map the stellar populations in the Galactic bulge and the adjacent plane and provide an exciting new tool for the study of the structure, content, and star-formation history of the Galaxy, as well as for investigations of the newly discovered star clusters, star-forming regions in the disk, high proper motion stars, asteroids, planetary nebulae, and other interesting objects.
