Data Release: First Data Release from Public Survey VINROUGE

Published: 19 Aug 2019

The primary goals of the Cycle 2 VISTA Public Survey "Vista Near infra-Red Observations Uncovering Gravitational wave Events" (VINROUGE) are to locate and characterise the electromagnetic counterparts of gravitational wave discovered events. This is achieved through wide field, multi-filter (Y, J, Ks) imaging of the error regions with VIRCAM on VISTA. This first data-release (DR1) contains imaging and catalogues obtained during the follow-up of three gravitational wave triggers from the second LIGO/Virgo science run (O2). The triggers were two black hole mergers GW 170809 and  GW 170814, and the kilonova transient GW 170817. For the latter, the gravitational wave counterpart was detected and identified as a binary neutron star merger. The observations of the three different fields cover 17, ~ 27 and 3.5 square degrees, respectively.

Other data products associated with the follow-up of the kilonova event on 17 August 2017 were previously released on 17 October 2017 (VISIR observations) and on 18 December 2017 (NaCO) under the Phase 3 collection GW170817.

The VINROUGE DR1 data products are available from the ESO Archive Science Portal or programmatically. More details about the release content can be found in the associated Phase 3 data release description. By accessing the VINROUGE DR1 products, the ESO community benefits from joint efforts by ESO, the PIs of the VISTA public survey projects and their collaborators, including CASU.
