We expand the census of star formation in compact group galaxies by Tzanavaris et al. (2010, Cat. J/ApJS/212/9) and collaborators with Swift UVOT, Spitzer IRAC and MIPS 24{mu}m photometry of a sample of 183 galaxies in 46 compact groups. After correcting luminosities for the contribution from old stellar populations, we estimate the dust-unobscured star formation rate (SFR_UV_) using the UVOT uvw2 photometry. Similarly, we use the MIPS 24 {mu}m photometry to estimate the component of the SFR that is obscured by dust (SFR_IR_). We find that galaxies which are MIR-active (MIR-'red'), also have bluer UV colours, higher specific SFRs, and tend to lie in HI-rich groups, while galaxies that are MIR-inactive (MIR-'blue') have redder UV colours, lower specific SFRs, and tend to lie in HI-poor groups. We find the SFRs to be continuously distributed with a peak at about 1M_{sun}_/yr, indicating this might be the most common value in compact groups. In contrast, the specific SFR distribution is bimodal, and there is a clear distinction between star-forming and quiescent galaxies. Overall, our results suggest that the specific SFR is the best tracer of gas depletion and galaxy evolution in compact groups.2016MNRAS.459.2948Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/459/2948CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJS/212/9 : X-ray sources in Hickson Compact Groups (Tzanavaris+, 2014)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/459/2948https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/459/2948http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/459/2948https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/459/2948https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/459/2948http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/459/2948GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/459/2948/groups (Studied groups)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/459/2948/groups?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/459/2948/groups?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/459/2948/groups?GETtext/xml+votable180.050000true7.858.44666670.0055555555555555566/1701 2432 2830 4215 4966 4990 5241 5635 5799 5970 8557 8935 13511 16690 16784 17492 17866 18071 18241 18757 19538 19619 19661 20355 22828 23182 24126 25769 27174 27620 27872 27918 28146 28251 28269 28272 28515 36621 36672 36740 38853 40294 469878.27688880188539e-21 5.517906024225661e-20https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/459/2948?format=asciiUVInfrareddefaultJ/MNRAS/459/2948/groupsStudied groupsrecnoRecord number assigned by the VizieR team.
