cds-question@unistra.fryoung-stellar-objectsradio-astronomyWe present observations of NH_3_ (1,1) and (2,2) lines in two flux-limited samples of IRAS sources selected according to colour criteria which should result in a high fraction of Young Stellar Objects. The first sample contains sources (named 'LOW') whose evolutionary status is essentially unknown, while the second sample contains sources (named 'HIGH') possibly associated with ultracompact HII regions, the distinction being based on the IRAS [25-12] colour.1996A&A...308..573Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/308/573CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+A/336/339 : VLA observations.
