log(M_mol)-log(R_eq) scaling relation for the clouds in the different environments. Colored density contours represent 1, 2, and 3 σ contours in their corresponding galactic environments, and the stars show the median values. The solid line in each plot is a linear regression for the clouds in a specific environment. The slope and intercept are given by m and n, respectively, and the correlation coefficient is given by r. The 2D histogram of the full sample is shown in gray. The blue line represents the linear regression for the clouds regardless of environment, and its fit parameters are represented in the blue box in the leftmost plot. The diagonal dotted lines represent constant Σ_mol lines at 10⁰, 10¹, 10², and 10³  M_⊙ pc⁻².
