cds-question@unistra.frsurveysplanetary-nebulaeh-ii-regionsThe AAO/UKST SuperCOSMOS H{alpha} Survey (SHS) was, when completed in 2003, a powerful addition to extant wide-field surveys. The combination of areal coverage, spatial resolution and sensitivity in a narrow imaging band, still marks it out today as an excellent resource for the astronomical community. The 233 separate fields are available online in digital form, with each field covering 25deg^2^. The SHS has been the motivation for equivalent surveys in the north, and new digital H{alpha} surveys now beginning in the south such as VPHAS+. It has been the foundation of many important discovery projects with the Macquarie/AAO/Strasbourg H{alpha} planetary nebula project being a particularly successful example. However, the full potential of the SHS has been hampered by lack of a clear route to acceptable flux calibration from the base photographic data. We have determined the calibration factors for 170 individual SHS fields, and present a direct pathway to the measurement of integrated H{alpha} fluxes and surface brightnesses for resolved nebulae detected in the SHS. We also include a catalogue of integrated H{alpha} fluxes for >100 planetary and other nebulae measured from the SHS, and use these data to show that fluxes, accurate to +/-0.10-0.14dex (~25-35%), can be obtained from these fields. For the remaining 63 fields, a mean calibration factor of 12.0 counts/pixel/R can be used, allowing the determination of reasonable integrated fluxes accurate to better than +/-0.2dex (~50%). We outline the procedures involved and the caveats that need to be appreciated in achieving such flux measurements. This paper forms a handy reference source that will significantly increase the scientific utility of the SHS.2014MNRAS.440.1080Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/440/1080CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/711/619 : {alpha}-element abundances in galactic PNe (Milingo+, 2010)J/MNRAS/431/2 : H{alpha} fluxes of Galactic planetary nebulae (Frew+, 2013)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/440/1080https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/440/1080http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/440/1080https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/440/1080https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/440/1080http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/440/1080GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/440/1080/table2 (A comparison of our SHS H{alpha} fluxes for over 100 PNe and other nebulae with independent integrated H{alpha} fluxes taken from the literature)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/440/1080/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/440/1080/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/440/1080/table2?GETtext/xml+votable180.050000true104.0610792-2.88550280.0055555555555555566/20980 21551 22047 28680 28713 28769 28792-28793 28819 28823 28826 28828-28829 28831 28848 28852 28854 28920 29070 29096 29105 29109 29118 29161 29163 29259 29277 29445 29448-29449 29454 29465 29509 29516 29544 29868 30243 30258 30303 30312 30337 30385 37172 37212 37232 37317 37364 37370 37721 37727 37783 37850 37875-37876 37884 37923 37930 38086 39251 39254 39259 39278 39281 39283 39371 39407 39419 39709 39745 39912 40075 40114 41404 41578 41608 41622 41640 41656 41658-41659 41665 41683 41690 41705 41713 41768 41806-41807 41809 41813 41826 42153 42228-42229 42335 42468 42828 43020https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/440/1080?format=asciiOpticaldefaultJ/MNRAS/440/1080/table1Data summary for all 233 SHS survey fieldsrecnoRecord number assigned by the VizieR team.
