Fig. B.1
HDO/H2O ratio for the three sources assuming excitation temperatures in the range 30–300 K and optically thin LTE emission. The green shaded area show the upper limit for the HDO/H2O ratio for the clustered protostars presented in Persson et al. (2014). The blue circle marks the value at the assumed excitation temperature of 124 K value.
