Notes. 

(a)

FWHM from the hyperfine fits over an effective area of radius Reff deduced from CLUMPFIND.

(b)

Total optical depth from the hyperfine fits over an effective area of radius Reff deduced from CLUMPFIND.

(c)

Virial Mass, and 3.5 mm dust continuum mass computed over an effective area of radius Reff (deconvolved with the beam) deduced from CLUMPFIND. Dust mass calculated for a temperature of 16 K.

(d)

Virial parameter defined in the text.

(e)

Average gas density over Reff.

(1)

NH2D emission with associated very weak or no dust emission (≤ 3σ).

(2)

Since there are two velocity components, no virial mass has been calculated.

(3)

Point like NH2D emission with associated very weak or no dust emission (≤ 3σ). Dust continuum mass is only a 3σ upper limit over the area integrated flux.

(4)

Point like NH2D emission with associated continuum emission (>3σ).
