Properties of the exponential disk of the total gas derived in this paper compared to the properties of the exponential dust disk determined by Meijerink et al. (2005).
Total gas exponential disk:
$\Sigma _{\rm gas}$ scale length $h_{\rm gas}$	7.6 $\pm 0.1$ kpc
Amplitude: $\Sigma^{\rm peak}_{\rm gas}$	17.8 $\pm 0.2$ $M_{\odot }$ pc^-2
disk/total mass-fraction gas	61%
Dust exponential disk:
dust scale length $h_{\rm d}$	6.3 kpc
Amplitude: $\Sigma^{\rm peak}_{\rm dust}$	0.77 $\pm 0.2$ $M_{\odot }$ pc^-2
disk/total mass-fraction dust	55%
