Fig. 9

Maps of the CH3CN rotational temperature (color image) and column density (contours) obtained with the XCLASS program. The labels have the same meaning as in Fig. 4. Contour levels range from 2 × 1013 to 1014 in steps of 1013 cm−2. Typical uncertainties on the values of the rotational temperature are 10–20%.
