As a continuation of the recent attempt by Ogura et al. (2007PASJ...59..199O), we have carried out BVIc photometry of four more BRC aggregates along with deeper re-observations of two previously observed BRCs. Again, quantitative age gradients are found in almost all the BRCs studied in the present work. Archival Spitzer/Infrared Array Camera data also support this result.2009MNRAS.396..964Chttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/396/964CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/246 : 2MASS All-Sky Catalog of Point Sources (Cutri+ 2003)J/AJ/123/2597 : H{alpha} stars and HH objects near BRCs (Ogura+, 2002)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/396/964https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/396/964http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/396/964https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/396/964https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/396/964http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/396/964GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/396/964/stars (Optical and near-IR photometry and physical)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/396/964/stars?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/396/964/stars?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/396/964/stars?GETtext/xml+votable180.050000true0.98791768.5628890.005555555555555556Cone search capability for table J/MNRAS/396/964/table6 (IRAC photometric magnitudes of the disk bearing candidates in BRCs 2, 27 and 13/14)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/396/964/table6?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/396/964/table6?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/396/964/table6?GETtext/xml+votable180.050000true1.061208368.54716670.005555555555555556Cone search capability for table J/MNRAS/396/964/table7 (J, H and K magnitudes of the sources used in the analysis (cf.
