Its footprint spans the Galactic latitude range -5° %3C b %3C +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.Original acknowledgement for data: 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.2014MNRAS.440.2036Dhttps://alasky.cds.unistra.fr/VPHAS/CDS_P_VPHAS_DR4_uSurveyResearchIsDerivedFromESO Science Archive ( http://archive.eso.org/wdb/wdb/adp/phase3_main/form?phase3_collection=VPHASplus&release_tag=4 )This HiPS is distributed under ODbL license by Unistra/CNRShttps://alasky.cds.unistra.fr/VPHAS/CDS_P_VPHAS_DR4_uhttps://alaskybis.cds.unistra.fr/VPHAS/CDS_P_VPHAS_DR4_u55926.213 58345.13464.96246722945867e-19 6.193244011264213e-19https://alasky.cds.unistra.fr/VPHAS/CDS_P_VPHAS_DR4_u/Moc.fitsOptical
