Notes. Correlations are computed between the scale sgal and shape σgal of the cloud mass spectra (from lognormal fits), total molecular cloud mass ∑Mmol, and various galactic properties across 66 galaxies. Nclouds is the total number of clouds within a galaxy, and Nclouds/Aenv is the number density of clouds within a galaxy. Σmol, Mmol, and Req are median cloud values per galaxy. Global galaxy properties (SFR, M★, atomic hydrogen mass 
, sSFR, Re, i) are taken from Leroy et al. (2021).
