Histograms showing PHANGS–ALMA sample properties. The top row shows CO luminosity (Section 4.6) and morphological T-type code from HyperLEDA (Paturel et al. 2003; Makarov et al. 2014). The middle row shows the ratio of SFR to M, i.e., the specific star formation rate, and the ratio of LCO to SFR, which can be scaled by αCO to calculate the molecular gas depletion time. The bottom row shows offsets from two scaling relations: the SFR–M “star-forming main sequence” and the mass–size relation. Aperture corrections have been applied to the LCO estimates used in the plots (Section 4.6.1). In panels relevant to sample selection, gray shading marks the region excluded by the main sample selection (Section 3). Note that our best estimates of each quantity have improved since selection, so that we selected some galaxies that we now believe miss the selection criteria. The darker histogram shows properties of galaxies in survey extensions that focus on early-type and very nearby galaxies.
