cds-question@unistra.frinfrared-sourcespre-main-sequence-starslate-type-starsinfrared-photometryThe results of a deep mid-IR ISOCAM survey of the L1551 dark molecular cloud are presented. The aim of this survey is a search for new YSO (Young Stellar Object) candidates, using two broad-band filters centred at 6.7 and 14.3{mu}m. Although two regions close to the centre of L1551 had to be avoided due to saturation problems, 96 sources were detected in total (76 sources at 6.7{mu}m and 44 sources at 14.3{mu}m). Using the 24 sources detected in both filters, 14 were found to have intrinsic mid-IR excess at 14.3{mu}m and were therefore classified as YSO candidates. Using additional observations in B, V, I, J, H and K obtained from the ground, most candidates detected at these wavelengths were confirmed to have mid-IR excess at 6.7{mu}m as well, and three additional YSO candidates were found.2004A&A...420..945Ghttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/420/945CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/350/883 : R CrA ISOCAM observations (Olofsson+, 1999)J/A+A/357/219 : Cha I ISOCAM observations (Persi+, 2000)J/A+A/372/173 : rho Ophiuchi cloud ISOCAM observations (Bontemps+, 2001)J/A+A/318/879 : IR photometry of L1551/IRS5 (Men'shchikov+ 1997)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/420/945https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/420/945http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/420/945https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/420/945https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/420/945http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/420/945GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/420/945/table2 (All ISOCAM sources in L1551 with additional optical, near-IR photometry and source comments)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/420/945/table2?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/420/945/table2?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/420/945/table2?GETtext/xml+votable180.050000true67.67958317.9750.0055555555555555566/23548-23549https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/420/945?format=asciiInfrareddefaultJ/A+A/420/945/table2All ISOCAM sources in L1551 with additional optical, near-IR photometry and source commentsRemRemarks (1)meta.notecharrecnoRecord number assigned by the VizieR team.
