cds-question@unistra.frstar-forming-regionsinterstellar-mediummolecular-cloudsmilky-way-galaxyradio-sourcesWe report studies of the relationships between the total bolometric luminosity (L_bol_ or L_TIR_) and the molecular line luminosities of J=1-0 transitions of H^13^CN, H^13^CO^+^, HCN, and HCO^+^ with data obtained from ACA observations in the 'ATOMS' survey of 146 active Galactic star-forming regions. The correlations between L_bol_ and molecular line luminosities L'_mol_ of the four transitions all appear to be approximately linear. Line emission of isotopologues shows as large scatters in L_bol_-L'_ mol_ relations as their main line emission. The log(L_bol_/L'_mol_) for different molecular line tracers have similar distributions. The L_bol_-to-L'_ mol_ ratios do not change with galactocentric distances (R_GC_) and clump masses (M_clump_). The molecular line luminosity ratios (HCN-to-HCO^+^, H^13^CN-to-H^13^CO^+^, HCN-to-H^13^CN, and HCO^+^-to-H^13^CO^+^) all appear constant against L_bol_, dust temperature (T_d_), M_clump_, and R_GC_. Our studies suggest that both the main lines and isotopologue lines are good tracers of the total masses of dense gas in Galactic molecular clumps. The large optical depths of main lines do not affect the interpretation of the slopes in star formation relations. We find that the mean star formation efficiency (SFE) of massive Galactic clumps in the 'ATOMS' survey is reasonably consistent with other measures of the SFE for dense gas, even those using very different tracers or examining very different spatial scales.2020MNRAS.496.2821Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/MNRAS/496/2821CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/A+AS/115/81 : A CS(2-1) survey of UC HII regions (Bronfman+, 1996)J/A+A/426/97 : SIMBA survey. 1.2-mm/IRAS sources (Faundez+, 2004)J/MNRAS/473/1059 : Complete sample of Galactic clump propertieshttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/MNRAS/496/2821https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/MNRAS/496/2821http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/MNRAS/496/2821https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/MNRAS/496/2821https://vizier.iucaa.in/viz-bin/votable?-source=J/MNRAS/496/2821http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/MNRAS/496/2821GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/MNRAS/496/2821/tablea1 (Compact objects identified in 3mm continuum emission)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/MNRAS/496/2821/tablea1?https://vizier.iucaa.in/viz-bin/conesearch/J/MNRAS/496/2821/tablea1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/MNRAS/496/2821/tablea1?GETtext/xml+votable180.050000true122.3849583-36.0870.0055555555555555566/21796 25782 25818 25826 28677 28690-28692 28694 28697-28698 28736 28744 28766-28767 28785 28972 28975 29034-29035 29072-29073 29075 29120-29121 29123 29125-29126 29145 29150-29151 29830 29851 30367 30441 30463 30895 30964-30965 30967 31085 31096 31117 31119 31126 31298 31827 31829 37852 37885 37917 38117 38181 39248 39250 39396 40862 41405-41406 41448 41451 41454-41455 41467 41470-41471 41590 41595 41597 41645 41653 41655 41660-41661 41671 41675 41680 41747 41749 41763-41764 41813 42151 42153-42155 42157-42159 42162 42164-42165 42172 42186-42187 42191 42199 42202-42205 42208 42285 42294 42296 42298 42300 42329 42332 42334 42339 42349 42368-42369 42371 42496 43013 43026 43042 44975 47786 47850https://cdsarc.cds.unistra.fr/viz-bin/moc/J/MNRAS/496/2821?format=asciiRadiodefaultJ/MNRAS/496/2821/tablea1Compact objects identified in 3mm continuum emissionSimbadSimbad column added by the CDSmeta.ref.urlcharrecnoRecord number assigned by the VizieR team.
