Third Data Release from the Galaxy Clusters At Vircam (GCAV) ESO VISTA Public Survey
Galaxy Clusters At Vircam (GCAV) is a survey (programme 198.A-2008, PI M. Nonino) belonging to the second cycle of ESO VISTA Public Surveys. It is aimed at observing 20 massive galaxy clusters in the infrared Y, J, and Ks bands. Those clusters have also been observed in many ground- and space-based programmes (e.g. CLASH, RELICS, HFF/ BUFFALO). The survey will mainly explore galaxy evolution over a wide, and still largely unexplored, diversity of cluster environments.
This third data release contains tile images, weightmaps and related source lists from data collected over the time period from October 2016 to March 2022 and corresponding to all the 525 OBs collected in the whole survey with ESO grade A and B. The tile images reach a typical sensitivity in AB magnitude of ~23.5 in Y, ~23.3 in J, and ~22.4 in Ks. The total area covered by the observations is ~38 deg2 and the total volume of the release is 2.1 TB.
Images and source lists of OBs released in DR1 (224 files) and DR2 (616 files) are replaced in DR3, with new astrometric reference system (GAIA-EDR3).
Full stack images and catalogues will be part of a future release.
All data are publicly accessible via the Science Portal or programmatically. More information is available in the accompanying release documentation. The DOI assigned to the data collection is https://doi.eso.org/10.18727/archive/26.
