Second band merged catalogue release from the VPHAS+ Public Survey.

This catalogue release from the ESO/VST Photometric H-alpha Survey of the Southern Galactic Plane and Bulge (VPHAS+) DR3 is now available via the Catalogue Facility. This band-merged catalogue covers about 1100 square degrees that correspond to 48% of the VPHAS+ footprint covering the Southern Galactic Plane. The catalogue is derived from the calibrated images of sufficient quality that have been acquired up to 30 March 2015 under ESO programme 177.D-3023(B,C,D,E, F, G, H).

The released catalog provides aperture photometry for 529 million primary detections, against a global calibration in the g, r and i bands using APASS as a reference survey. In this catalogue, the primary detections are supported by parameters providing information on the nature of each source detection and the total catalogue volume is about 0.44 terabytes.

The VPHAS+ second catalogue release was generated by the data flow managed by the Wide Field Astronomy Unit (WFAU) in Edinburgh. It is accompanied by a comprehensive description.
