Table 2

Overview of the column densities for D2O, HDO, and HO derived with the best-fit synthetic spectrum model (Nmodel) and with the fitted Gaussian profiles (Nfit).

Molecule Nmodel (cm−2) Nfit (cm−2) FWHM (km s−1) vLSR (km s−1) Tex (K)
L483
D2O 1.1 × 1015 1.7 × 1015 (4.5, 5.2) (1.75, 7.65) 165
HDO 1.1 × 1017 1.2 × 1017 (4.9, 5.7) (1.75, 7.65) 165
HO 5.1 × 1016 5.9 × 1016 (6.2, 7.1) (1.75, 7.65) 165

D2O 3.5 × 1015 4.0 × 1015 4.25 7.6 220
HDO 2.5 × 1017 1.9 × 1017 4.0 7.9 220
HO 6.3 × 1016 7.1 × 1016 5.65 7.9 220

Notes. The reported full width at half maximum (FWHM) and vLSR are for the synthetic spectrum model. A source size of 0.′′2 is assumed for both sources for all molecules.
