Fig. 4


Example of the fit performed with MCWeeds for CH3OH. The best fit model is shown in red. The lines not reproduced by the model are contaminating species and are excluded from the spectral ranges used for the fit (cf. Table 2) The top panel show the results for an IRw source and the bottom panel for an Hii. The νt = 1 band is visible between ~ 337 500 and ~380 000 MHz.
