The profiles were modelled by an exponential disk and a spherical bulge described either by the R^1/4^ law or by an exponential function. Half of the galaxies were well fitted by both bulge models, whereas for 35% the exponential function was a better choice. Special care was taken on eliminating superpositions of the companion galaxies. The mean B-band central surface brightness {mu}_0_was found to be 21.5mag/arcsec^2^, which is near to the value originally found by Freeman (1970ApJ...160..811F), but the scatter was fairly large. Galaxy interactions have strongly modified the disks in many of the galaxies in the sample. For example, six of them had extremely flat brightness profiles outside the exponential part of the disk, and many showed significant isophotal twists.2000A&AS..141..103Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+AS/141/103CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+AS/141/103https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+AS/141/103http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+AS/141/103https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+AS/141/103https://vizier.iucaa.in/viz-bin/votable?-source=J/A+AS/141/103http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+AS/141/103GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+AS/141/103/table1 (The position angle and inclination of the disk)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+AS/141/103/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+AS/141/103/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+AS/141/103/table1?GETtext/xml+votable180.050000true20.862530.7716670.0055555555555555566/2199 2359 2452 4328 4839 5596 7228 7230 7599 8546 9791 10433 10628 11372 16091 19283 23921 27715 28225 28278 32745https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+AS/141/103?format=asciiOpticalInfrareddefaultJ/A+AS/141/103/table1The position angle and inclination of the diskrecnoRecord number assigned by the VizieR team.
