We combine the U-band photometry with literature data to compute accretion luminosity and mass accretion rates from the U-band excess emission for all objects (187) detected by Spitzer in the FORS1 field and classified by Hernandez et al. (2007, Cat. J/ApJ/662/1067) as likely members of the cluster.2011A&A...525A..47Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/525/A47CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/AJ/128/2316 : BVRIJHKs photometry in sigma Ori cluster (Sherry+, 2004)J/MNRAS/356/89 : sigma Ori low-mass stars (Kenyon+, 2005)J/ApJ/662/1067 : Spitzer observations of sigma Orionis (Hernandez+, 2007)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/525/A47https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/525/A47http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/525/A47https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/525/A47https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/525/A47http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/525/A47GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/525/A47/tablec2 (U-band and collected literature photometry)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/525/A47/tablec2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/525/A47/tablec2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/525/A47/tablec2?GETtext/xml+votable180.050000true84.46288-2.435420.005555555555555556Cone search capability for table J/A+A/525/A47/table23 (Accretion properties of the class II objects and objects with transitional and evolved disks (table2) and objects taken from Gatti et al.
