obs_description = The VST Photometric Halpha Survey of the Southern Galactic Plane and Bulge (VPHAS+) is surveying the southern Milky Way in u, g, r, i and Halpha at ?1 arcsec angular resolution. Its footprint spans the Galactic latitude range -5° < b < +5° at all longitudes south of the celestial equator. Extensions around the Galactic Centre to Galactic latitudes ±10° bring in much of the Galactic bulge. This European Southern Observatory public survey, begun on 2011 December 28, reaches down to ?20th magnitude (10?) and provides single-epoch digital optical photometry for ?300 million stars. This HiPS has been built from images from DR4 release ; the background has been globally corrected using Montage, developed at IPAC.
obs_ack = Based on data obtained from the ESO Science Archive Facility with DOI(s): https://doi.org/10.18727/archive/65 . The VPHAS+ data were produced by the VPHAS+ collaboration. This research made use of Montage; we would like to thank John Good for his valuable advice.
