VVVX is an ESO Public Survey that was approved as part of the second cycle of Public Surveys with VISTA. This project extends the VISTA Variables in the Via Lactea (VVV) survey parameter space both in area coverage and time. Primarily, VVVX includes portions of the southern galactic plane that were not covered by VVV. Furthermore, it will provide additional epochs to the VVV area in order to improve proper motion precision and keep monitoring the long term variable stars.
Data Release: VVVX Public Survey First Data Release
The data are taken under the ESO Programme 198.B-2004 with VIRCAM. This first release contains observations of about 590 square degrees, typically covered in three filters: H, J and Ks. Data were acquired between July 2016 and August 2017. These master data will be supplemented by the next releases of the Ks time series. All tiles, their confidence maps and extracted source lists, in addition to the corresponding pawprints, were processed with version 1.5 of the CASU pipeline.
