Table 2: Conversion factors of the line intensity in erg s^-1 cm^-2 into the velocity integrated main beam temperature observed at the IRAM and JCMT telescopes respectively, for the five lines observed towards IRAS 16293-2422 (Parise et al. 2005). Last column quotes the observed towards IRAS 16293-2422 (Parise et al. 2005).^a Predicted flux from the model simply converted into K km s^-1 using the conversion factor. ^b Predicted flux derived using an accurate convolution of the signal with the telescope beam.
