The images in filters u,g,r,i from the Sloan Digital Sky Survey database are used for photometry. The following model-independent parameters are obtained: integrated magnitudes and colours, effective radii and the respective surface brightnesses, optical and Holmberg radii. On results of the radial surface brightness profile analysis, their central values and scalelengths of model discs are derived. The colours of the outer parts of void galaxies are examined and compared to those of the model evolutionary tracks of the PEGASE2 package. This allowed to obtain estimates of the time since the epoch of star formation T_SF_. Among the latter group, the low-luminosity objects with M_B_>-13.2 dominate. The derived integrated absolute magnitudes and colours are used for galaxy stellar mass estimates. All available data on integrated galaxy HI fluxes are used to derive their parameter M(HI)/L_B_ and to estimate their gas mass-fraction. The small ~10% subgroup of the most gas-rich galaxies, with M(HI)/L_B_>2.5, shows gas mass-fractions reaching (94-99)%. Many of these objects also show atypically blue colours of their outer parts. To check possible statistical differences of void galaxy properties and galaxy samples formed with more general criteria, we compared the void sample galaxy parameters with those of 195 galaxies from the Equatorial Survey (ES), formed as a part of the blind HI survey HIPASS. In the common luminosity range (-18.5<M_g_<-13.5) the compared samples show similarity. The lowest luminosity void galaxies differ from the main ES sample. However, there are also ~7% faint so called 'inchoate' galaxies among ES sample with the elevated parameter M(HI)/L_B_, majority of which are situated far from massive neighbours and are probably the analogs of void galaxies.2014AstBu..69..247Phttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/other/AstBu/69.247CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/415/1188 : Galaxies in the Lynx-Cancer void (Pustilnik+, 2011)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/other/AstBu/69.247https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/other/AstBu/69.247http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/other/AstBu/69.247https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/other/AstBu/69.247https://vizier.iucaa.in/viz-bin/votable?-source=J/other/AstBu/69.247http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/other/AstBu/69.247GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/other/AstBu/69.247/lc_photo (Photometric parameters of galaxies Lynx-Cancer void)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/other/AstBu/69.247/lc_photo?https://vizier.iucaa.in/viz-bin/conesearch/J/other/AstBu/69.247/lc_photo?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/other/AstBu/69.247/lc_photo?GETtext/xml+votable180.050000true96.58737524.65555560.0055555555555555566/4121 4149 4181 4213 4324 4334 4352 4575 4587 4602 4650 4756 4887 4912 4933 4946 4948 4975 4983 5039 5059 5116 5258 5263 5267 5280 5283-5285 5287 5358-5359 5633 5635-5636 5641 5660 5685-5686 5738 5758 5781 5834 5848-5849 6167 6204 6296 6320 6375 6399 6419 6443 6488 6500 6502 6548 6553 6560 6604-6605 6619 6623 6649 6752 6932 6981 7216 22495 24042 27375 27383https://cdsarc.cds.unistra.fr/viz-bin/moc/J/other/AstBu/69.247?format=asciiOpticalInfrareddefaultJ/other/AstBu/69.247/lc_photoPhotometric parameters of galaxies Lynx-Cancer voidSimbadNameSimbad column added by the CDSmeta.idcharNameGalaxy name (1)meta.id;meta.maincharrecnoRecord number assigned by the VizieR team.
