cds-question@unistra.frgalaxiesphotometrysurface-photometryIntrigued by the initial report of an extended luminosity distribution perpendicular to the disk of the edge-on Sc galaxy NGC 5907, we have obtained very deep exposures of this galaxy with a Schmidt telescope, large-format CCD, and intermediate-band filters centered at 6660 {AA} and 8020 {AA}. These two filters, part of a 15-filter set, are custom designed to avoid the brightest (and most variable) night skylines. As a result, our images are able to go deeper with lower sky noise than those taken with broadband filters at similar effective wavelengths: e.g., 0.6 e^-^ arcsec^-2^ s^-1^ for our observations versus 7.4 e^-^ arcsec^-2^ s-1 for the R-band measures of Morrison et al. (1994AJ....108.1191M). In our assessment of both random and systematic errors, we show that the flux level where the errors of observation reach 1 mag arcsec^-2^ are 29.00 mag arcsec^-2^ in the 6660 {AA} image (corresponding to 28.7 in the R band) and 27.4 mag arcsec^-2^ in the 8020 {AA} image (essentially on the I-band system)1999AJ....117.2757Zhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/117/2757CatalogResearchIsServedByTAP VizieR generic servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AJ/117/2757https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AJ/117/2757http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AJ/117/2757https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AJ/117/2757https://vizier.iucaa.in/viz-bin/votable?-source=J/AJ/117/2757http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AJ/117/2757GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapOpticaldefaultJ/AJ/117/2757/table5Perpendicular surface brightness profiles of NGC 5907 in the 6660 and 8020 {AA} imagesrecnoRecord number assigned by the VizieR team.
