VizieR Online Data Catalog: Resolved molecular gas in nearby galaxies (Chown+, 2021)

The sample is selected from the EDGE survey (Bolatto et al. 2017ApJ...846..159B, Cat. J/ApJ/846/159). The typical angular resolution of EDGE CO maps is 4.5arcsec, and the typical H2 surface density sensitivity before deprojecting galaxy inclination is 11M_ȯpc^-2. Every EDGE galaxy has optical integral field unit (IFU) data from CALIFA, allowing joint studies of the content and kinematics of cold gas (H₂), ionized gas, and stellar populations, all with ~kpc spatial resolution. We processed the CO data for all 126 EDGE galaxies, and as a starting point we selected the 95 galaxies which had at least one detected pixel after smoothing to 6.6arcsec resolution and regridding the moment-0 maps with 6arcsec pixels. We then selected those galaxies with inclinations less than 75°, leaving 83 galaxies.

We downloaded 2° by 2° cut-outs (pixel size 1.375arcsec) of WISE 12μm (W3) flux and uncertainty for each galaxy from the NASA/IPAC Infrared Science Archive. The background for each galaxy was estimated using the IDL package software for source extraction (SEXTRACTOR; Bertin & Arnouts 1996A&AS..117..393B), with default parameters and with the corresponding W3 uncertainty map as input.
