Notes.

(a)

calculated quantities; the mean CO(1-0)–H2 conversion factor is αCO = 1.7 ± 0.4 M(K km s−1 pc2)−1 (Vollmer et al. 2017).

(b)

assumed quantities; all other columns are input quantities from Downes & Solomon (1998).

(c)

Arp220D, Arp220W, and Arp220E refer to the Disk, Western, and Eastern components, respectively.

(d)

Garcia-Carpio et al. (2008)

(e)

A conversion factor of /LTIR = 1.7 × 10−10 M yr−1 was assumed

(f)

A rotation curve of the form vrot = vmax(1 − exp(−R/lflat)) was assumed.
