The virial mass $M_{vir}$ against the luminous mass $M_{lum}$ $M_\mathrm{lum}$  for the clouds, colored by galactocentric distance $R_{gal}$. $R_\mathrm{gal}$.  Fit lines are for M83 (blue line) and a $M_{lum}=M_{vir}$ $M_\mathrm{lum}=M_\mathrm{vir}$  relationship (green line). \label{fig:mlummvir}
