Notes. ^(a) Temperatures are determined from single grey body fits assuming an emissivity $\beta = 2$ , and excluding the 70 $\mu$ m data points. ^(b) Fluxes are in Jy. Luminosities only include flux from 60 $\mu$ m to 600 $\mu$ m and are based on fluxes within a Hi-GAL resolution element. ^(c) Masses estimated from $\lambda$ = 500 $\mu$ m in a 37 $^{\prime\prime}$ beam, assuming OH94 opacities at t = 10⁵ years, n = 10⁶ cm^-3 for thin ice mantles (first number) and un-evolved MRN dust with no mantles (second number).
