Building on the original COLD GASS survey, we present here the full sample of 532 galaxies with CO (1-0) measurements from the IRAM 30m telescope. The sample is mass-selected in the redshift interval 0.01<z<0.05 from the Sloan Digital Sky Survey (SDSS) and therefore representative of the local galaxy population with M_*_>10^9^M_{sun}_. The CO (1-0) flux measurements are complemented by observations of the CO (2-1) line with both the IRAM 30 m and APEX telescopes, HI observations from Arecibo, and photometry from SDSS, WISE, and GALEX. Combining the IRAM and APEX data, we find that the ratio of CO (2-1) to CO (1-0) luminosity for integrated measurements is r_21_=0.79+/- 0.03, with no systematic variations across the sample. The CO (1-0) luminosity function is constructed and best fit with a Schechter function with parameters L_CO_^* ^=(7.77+/-2.11)x10^9^K.(km/s).pc^2^, {phi}^*^=(9.84+/-5.41)x10^-4^Mpc^-3^, and {alpha}=-1.19+/-0.05. With the sample now complete down to stellar masses of 10^9^M_{sun}_, we are able to extend our study of gas scaling relations and confirm that both molecular gas fractions (f_H2_) and depletion timescale (t_dep_(H2)) vary with specific star formation rate (or offset from the star formation main sequence) much more strongly than they depend on stellar mass. Comparing the xCOLD GASS results with outputs from hydrodynamic and semianalytic models, we highlight the constraining power of cold gas scaling relations on models of galaxy formation.2017ApJS..233...22Shttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJS/233/22CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/MNRAS/476/875 : xGASS catalog (Catinella+, 2018)https://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/ApJS/233/22https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/ApJS/233/22http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/ApJS/233/22https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/ApJS/233/22https://vizier.iucaa.in/viz-bin/votable?-source=J/ApJS/233/22http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/ApJS/233/22GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/ApJS/233/22/catalog (Identifiers and basic properties, star formation rates and IR luminosity, spectral information, IRAM CO (1-0) and CO (2.1) measurements, and APEX CO(2-1) observations (tables 1, 3, 6))https://vizier.cds.unistra.fr/viz-bin/conesearch/J/ApJS/233/22/catalog?https://vizier.iucaa.in/viz-bin/conesearch/J/ApJS/233/22/catalog?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/ApJS/233/22/catalog?GETtext/xml+votable180.050000true2.0865415.156010.0055555555555555565/2066 6/526-527 545 547-549 552 554-555 4107 4111 4123 4144 4155-4156 4162 4165 4168-4169 4171 4179-4180 4182 4185 4188 4193 4195 4197 4203 4209-4210 4214 4223 4236 4288 4298 4301-4302 4312 4318 4328-4329 4349 4352 4357 4359 4369-4370 4381 4401 4452 4457 4520 4569 4584 4589 4603 4650 4652-4653 4714 4719 4730 4734 4742 4749 4752 4756 4801 4804 4806 4811 4820 4839 4845 4863 4866 4870 4880 4907 4919 4921 4927 4933 4948 4985 4993 5001 5034 5121 5148 5175 5221 5230 5295 5657 5672 6217 6234 6437 8211-8213 8225 8232 8245-8247 8254 8270 8282-8283 8291 8300 8339 8344-8345 8350 8390 8509 8670 8702 8704-8705 8719 8723 8732 8736 8744 8746-8748 8835 8839 8841 8862 8922 8924-8926 8939 8942 9098 9111 9126 9170 10285 10287 10297 10319 10334 10339 10350 10363 10378-10379 10383 10392 10397 10400-10401 10405 10440 10514 10517 10531 10538 10765 17833 18009 18014 18075 18096-18097 18299 18301-18302 18385 18387 18389 18402-18403 18406 18409-18411 18413-18414 18794 18865 19319 19325 19382-19383 19385 19387 19390 19411 19416-19417 19426 19430 19432 19672-19673 19678 19684 19689 19693 19698 19735 19737 19742 19748-19749 19752 19754 19841-19842 19981 19983 19987 19992 19994 19996 19998 20002-20003 20005-20006 20016-20017 21976 22008 22361 22364 22388 22397 22399 25957 25966 25977 25979 25981-25982 26030 26040-26041 26046 26049 26059-26060 26063-26065 26070 26072-26073 26075 26083 26088 26097 26104 26109 26236 26238 26295 26311 26318-26319 26326 26328 26334 26343 26349 26366 26385 26388 26393 26432 26437 26462 26487 26509 26520 26524 26533 26540-26541 26548 26553 26561 26563 26572-26573 26971 26988 27003 27061 27071 27087 27090 27094 27096 27109 27120 27127 27247 27259 27314 27324 27338 27343 27361 27364 27368 27381 27383-27384 27391 27399 27401 27414 27421-27424 27430 27438 27457-27458 27480 27486 27503 27507-27508 27510 27514 27516 27522 27527 27536-27537 27554 27560-27562 27586 27589-27591 27593-27594 27597 27602-27604 27616 27618 27620 27652 27654 27726 27729 27731 27747 27749 27755 27763 27774 27806 27809 27814 27857 27860 27872 27888 27910 27915 27926 27928 27937 27942 27946 27951 28081 28126 28148 28154 28158 28169 28171 28178 28180 28189 28193-28194 28224 28228 28232 28299 28346 28371 28403 28414 28461 28464 28472 28522 28554 28619 31419 31443 31473 31654https://cdsarc.cds.unistra.fr/viz-bin/moc/J/ApJS/233/22?format=asciiRadiodefaultJ/ApJS/233/22/catalogIdentifiers and basic properties, star formation rates and IR luminosity, spectral information, IRAM CO (1-0) and CO (2.1) measurements, and APEX CO(2-1) observations (tables 1, 3, 6)R50kpc?
