Our sample consists of 1781 luminous (M_r'_<-19.3mag) galaxies in the magnitude range 15.5mag<r'<17mag and in the redshift range 0.04<z<0.2. Although we have classified tidal features according to their morphology (e.g., streams, shells, and tails), we do not attempt to interpret them in terms of their physical origin (e.g., major versus minor merger debris). Instead, we provide a catalog that is intended to provide raw material for future investigations which will probe the nature of low surface brightness substructure around galaxies. We find that around 12% of the galaxies in our sample show clear tidal features at the highest confidence level. This fraction rises to about 18% if we include systems with convincing, albeit weaker tidal features, and to 26% if we include systems with more marginal features that may or may not be tidal in origin. These proportions are a strong function of rest-frame color and of stellar mass. Linear features, shells, and fans are much more likely to occur in massive galaxies with stellar masses >10^10.5^M_{sun}_, and red galaxies are twice as likely to show tidal features than are blue galaxies.2013ApJ...765...28Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/765/28CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/cfht : Log of CFHT Exposures (CADC, 1979-)II/317 : The CFHTLS Survey (T0007 release) (Hudelot+ 2012)J/ApJ/736/24 : VI photometry of sources in the halo of NGC253 (Bailin+, 2011)J/ApJS/186/427 : Detailed morphology of SDSS galaxies (Nair+, 2010)J/AJ/130/2647 : Tidal features of 126 nearby red galaxies (van Dokkum+, 2005)J/ApJ/588/218 : i*g* photometry of SDSS EDR galaxies (Abraham+, 2003)J/ApJS/107/1 : Morphologies of distant galaxies II (Abraham+ 1996)J/MNRAS/274/1107 : Morphological classifications of APM galaxies (Naim+ 1995)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/765/28https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/765/28http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/765/28https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/765/28https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/765/28http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/765/28GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/765/28/table4 (Master data table of selected galaxies)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/765/28/table4?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/765/28/table4?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/765/28/table4?GETtext/xml+votable180.050000true30.69014694-11.165118060.0055555555555555564/714 2298 5/2687 2851 2854 2860 2861 2944 2945 4372 4373 4375 4416 4417 4418 4420 4424 4758 4759 4764 4766 4767 9151 9198 10230 10233 10236 10237 10238 6/10741 10742 10743 10745 10747 11092 11093 11398 11399 11401 11402 11403 11422 11448 11449 11450 11452 11788 11792 17497 17525 17676 17677 17678 17688 17700 19021 19023 19025 19026 19027 19030 19031 19047 19053 19060 19061 19062 19153 19156 19157 19232 19240 19242 21840 21841 27298 36599 36603 36747 36750 36786 36798 40909 40910 40911 40929 40931 40940 40941 40943 40956 40957 40958https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/765/28?format=asciiOpticalInfrareddefaultJ/ApJ/765/28/table4Master data table of selected galaxiesrecnoRecord number assigned by the VizieR team.
