cds-question@unistra.frThe 7 and 15{mu}m observations of selected fields in the Galactic Plane obtained with ISOCAM during the ISOGAL program offer an unique possibility to search for previously unknown YSOs, undetected by IRAS because of lower sensitivity or confusion problems. In a previous paper (Felli et al., 2000, Cat. <J/A+A/362/199>) we established criteria of general validity to select YSOs from the much larger population of Post Main Sequence (Post-MS) stars present in the ISOGAL fields by comparing radio and IR observations of five fields located at l~45{deg}. The selection was based primarily on the position of the point sources in the [15]-([7]-[15]) diagram, which involves only ISOGAL data and allows to find possible YSOs using the survey data alone. In the present work we revise the adopted criteria by comparing radio-identified ultra-compact HII regions and ISOGAL observations over a much larger region. The main indications of the previous analysis are confirmed, but the criteria for selecting YSO candidates had to be revised to select only bright objects, in order to limit the contamination of the sample by Post-MS stars. The revised criteria ([15]<=4.5, [7]-[15]>=1.8) are then used to extract YSO candidates from the ISOGAL Point Source Catalogue in preparation. We select a total of 715 YSO candidates, corresponding to ~2 of the sources with good detections at 7 and 15{mu}m. The results are presented in a table form that provides an unique input list of small diameter, <=6", Galactic YSO candidates. The global properties of the sample of YSO candidates are briefly discussed.2002A&A...392..971Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/392/971CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toB/iso : ISO Observation Log of validated data (ISO Data Centre, 2001)B/denis : The DENIS database (Epchtein+, 1999)J/A+A/362/199 : YSOs in the l=+45 ISOGAL field (Felli+, 2000)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/392/971https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/392/971http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/392/971https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/392/971https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/392/971http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/392/971GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/392/971/table3 (YSO candidates in the ISOGAL survey)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/392/971/table3?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/392/971/table3?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/392/971/table3?GETtext/xml+votable180.050000true218.11391-60.7606380.0055555555555555565/7206 6/3290 3649 14267 14307 14353 14619 15670 28802-28803 28806-28808 28810-28811 28813-28815 28823 28828 28830-28831 28848-28849 28853 28874-28875 28878 28882 28890 28896-28897 28900 28902 28912 28914-28916 29090 29096 29100-29101 29115 29118 29457 29463 29505-29508 29510 29523 29529 30219 30241 30258-30259 30262 30265 30268-30269 30419 30622 30641 30692 30712 30716 30718 41768 41770 41804 41806 42158 42173 42216 42224-42226 42378-42379 42393 42434-42435 42441 42445 42454 42457 42460-42461 42463 425001.324299464694731e-20 2.689546822829005e-19https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/392/971?format=asciiInfrareddefaultJ/A+A/392/971/table3YSO candidates in the ISOGAL surveyIGfieldISOGAL field designationmeta.idcharrecnoRecord number assigned by the VizieR team.
