VizieR Online Data Catalog: 78 Stripe82 galaxies masses (Bertemes+, 2018)

Our sample is chosen with the goal of cross-calibrating CO- and dust-based gas masses on, first of all, the same set of galaxies, and secondly, only galaxies with known metallicities based on strong optical nebular lines.

To ensure that the dust method can be applied to our sample in addition to the CO method, we rely on IR data from the Herschel Stripe82 Survey (HerS; Viero et al., 2014ApJS..210...22V, Cat. J/ApJS/210/22 and the Wide-field Infrared Survey Explorer (WISE; Wright et al., 2010AJ....140.1868W, See Cat. II/311) All-Sky Release.

Our CO observations were taken with the IRAM 30-m telescope using the Eight Mixer Receiver (EMIR) with the Wideband Line Multiple Autocorrelator (WILMA) backend. For all targets, the redshifted CO(1-0) line could be observed in the upper sideband of the 3mm E090 band (89-1177GH). We additionally observed the redshifted CO(2-1) line whenever it was covered by the same frequency set-up for the 1.3 mm E230 band. This was the case for 56 out of our 78 galaxies. Exposure times range from 6 to 108min with median value (texp)=36min, adjusted on an object-to-object basis until a significant (>5σ) detection was obtained.
