VPHAS+ DR4 u filter HiPS

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 (10σ) 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.
