cds-question@unistra.frsurveysinfrared-sourceshst-photometryOur Hubble Space Telescope/Near-Infrared Camera and Multi-Object Spectrometer (HST/NICMOS) Paschen {alpha} survey of the Galactic Centre, first introduced by Wang et al. (2010MNRAS.402..895W), provides a uniform, panoramic, high-resolution map of stars and an ionized diffuse gas in the central 416arcmin^2^ of the Galaxy. This survey was carried out with 144 HST orbits using two narrow-band filters at 1.87 and 1.90um in NICMOS Camera 3. In this paper, we describe in detail the data reduction and mosaicking procedures followed, including background level matching and astrometric corrections. We have detected ~570000 near-infrared (near-IR) sources using the 'starfinder' software and are able to quantify photometric uncertainties of the detections.2011MNRAS.417..114Dhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/417/114CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/417/114https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/417/114http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/417/114https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/417/114https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/417/114http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/417/114GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/417/114/table2 (HST/NICMOS GC survey catalogue)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/417/114/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/417/114/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/417/114/table2?GETtext/xml+votable180.050000true266.27877-29.143640.005555555555555556Cone search capability for table J/MNRAS/417/114/Palpha (Paschen {alpha} emitting candidates)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/417/114/Palpha?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/417/114/Palpha?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/417/114/Palpha?GETtext/xml+votable180.050000true266.62478-28.780010.0055555555555555566/28827 28830https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/417/114?format=asciiInfrareddefaultJ/MNRAS/417/114/table2HST/NICMOS GC survey cataloguerecnoRecord number assigned by the VizieR team.
