cds-question@unistra.frsurface-photometryWe perform detailed surface photometry, based on B- and/or R-band CCD images of 92 faint galaxies. They are a subsample of those galaxies which were studied by Hopp et al. (1994) in the direction of three nearby voids. We derive integral photometric parameters and radial surface brightness profiles and compare them to those of several faint galaxy samples, located in different environments, and of a bright field galaxy sample. According to the obtained photometric characteristics, our sample is a mixture of intrinsically bright and faint galaxies, about 60% of them belonging to the bright subsample (M_B_<-19.0). These bright ones show mean characteristics of typical Freeman's disks and are mainly located in the background of the observed voids. The faint subsample (M_B_>=-19.0) has parameters typical for the low-surface-brightness (LSB) galaxies. There are a few well isolated galaxies both among the bright and faint subsamples.1996A&AS..117..261Vhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/117/261CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/117/261https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/117/261http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/117/261https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/117/261https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/117/261http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/117/261GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/117/261/table5 (Observed model-free photometric data in B and colour characteristics)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/117/261/table5?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/117/261/table5?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/117/261/table5?GETtext/xml+votable180.050000true160.7026-0.445570.005555555555555556Cone search capability for table J/A+AS/117/261/table6 (Observed model-free photometric data in R)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/117/261/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/117/261/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/117/261/table6?GETtext/xml+votable180.050000true196.8043933.661470.0055555555555555566/10428-10430 18075 18085 18093 18095 18343 18354 19456 19545 19548 19652-19653 19660 19666 19674 19719 19722-19723 19728 19731 19742 19752 19754 19756 19815 19840 26836 26871 26876 27043-27044 27046 27051 27057 27220 27223https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/117/261?format=asciiOpticaldefaultJ/A+AS/117/261/table5Observed model-free photometric data in B and colour characteristicsrecnoRecord number assigned by the VizieR team.
