cds-question@unistra.frinfrared-sourcesinterstellar-mediumIn an ongoing effort to identify and study high-mass protostellar candidates we have observed in various tracers a sample of 235 sources selected from the IRAS Point Source Catalog (Cat. <II/125>), mostly with delta<-30{deg}, with the SEST antenna at millimeter wavelengths. The sample contains 142 Low sources and 93 High, which are believed to be in different evolutionary stages. Both sub-samples have been studied in detail by comparing their physical properties and morphologies.2006A&A...447..221Bhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/447/221CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toII/125 : IRAS catalogue of Point Sources, Version 2.0 (IPAC 1986)J/A+A/432/921 : Massive protostellar candidates (Fontani+, 2005)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/447/221https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/447/221http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/447/221https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/447/221https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/447/221http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/447/221GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/447/221/table1 (Observed IRAS sources)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/447/221/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/447/221/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/447/221/table1?GETtext/xml+votable180.050000true123.995833-36.1383330.0055555555555555565/9482 9812 10420 10543 6/13050 14352 14355 14614 14690 28806 28808-28809 28812-28813 28815 28824-28825 28890 28900-28901 28916 28919 29112 29162 29529 29556 30244-30245 30259 30317 30341 30405 30416-30417 30616 30715 37207 37244 37331 37334-37335 37341 37343 37361 37364 37366 37369 37372 37374 37752 37844 37846 37848 37850 37872 37882 37887 37889 37894-37895 37897 37900 37902 37923 37932 37934 38016 38024-38026 38032 39267 39273 39375 41598-41599 41652 41655-41656 41660-41661 41663 41673 41676-41678 41684 41686 41691 41706 41758 41766 41770 41772 41776-41777 41779-41782 41801 41803-41804 41806 41809 41813-41816 41824 42154 42159 42169-42171 42211 42213 42216 42224-42225 42227-42229 42378-42379 42381-42382 42389 42392-42393 42397 42407 42435-42437 42441 42444 42449-42451 42456-42458 42460 42496-42497 42499 42512 42516 43015 43018-43019 43021 43024 43041https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/447/221?format=asciiInfrareddefaultJ/A+A/447/221/table1Observed IRAS sourcesn_Lum[cfghi] Note (2)meta.notecharrecnoRecord number assigned by the VizieR team.
