cds-question@unistra.frastrophysical-masersradio-astronomyCS J=1-0 and NH(J,K)=(1,1) observations toward a large sample of H2O maser regions are reported. A total of 172 sources were observed. 107 were observed in CS and 164 in NH_3_. The main purpose of this work was to study the relationship between the parameters that characterize the high velocity H2O maser emission, which originates in very small (about 10 AU) and very dense (10^7-10^9/cm^3^) regions, and those that characterize the molecular emission coming from quiescent, more extended (0.1-1.0 pc) high density (10^4-10^5/cm^3^) regions, traced by the CS and NH_3_ emissions. The observations were carried out between 1986 and 1990 with the 37 m radio telescope at Haystack Observatory The emission of the (J,K)=(1,1) inversion transition of the NH_3_ molecule at 23.694496 GHz, and the emission of the J=1->0 rotational transition of the CS molecule at 48.990968 GHz were observed.1996ApJ...463..205Ahttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/463/205CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJ/463/205https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJ/463/205http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJ/463/205https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJ/463/205https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJ/463/205http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJ/463/205GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJ/463/205/table1 (*Regions with known H2O maser emission)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJ/463/205/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJ/463/205/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJ/463/205/table1?GETtext/xml+votable180.050000true2.84075258.8394510.0055555555555555565/7278 6/342 859 862 3005 3011 3198 3290 3649 14052 14063 14287 14306 14309 14314 14317 14358 14359 14594 14621 14622 14624 14689 14704 15363 15468 15473 15667 15681 15759 15965 19279 21436 21439 21456 21457 21458 21523 21645 22805 22855 22873 22876 23637 23764 23798 23969 23982 24189 24325 24499 24507 24554 28808 28809 28812 28825 28826 28827 28828 28829 28830 28874 28900 28912 28918 28919 29070 29091 29095 29096 29097 29100 29101 29103 29116 29118 29461 29463 29504 29506 29510 29511 29522 29529 29532 29533 29535 30218 30245 30258 30259 30262 30263 30268 30269 30312 30313 30318 30319 30328 30366 30405 30595 30618 30622 30624 30644 30691 30694 32015 39909 42444 42445 42451 42455 42456 42457 42460 42461https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJ/463/205?format=asciiRadiodefaultJ/ApJ/463/205/table1*Regions with known H2O maser emissionrecnoRecord number assigned by the VizieR team.
