Table 2:

Excitation temperature and column densities.

Approach 		Component T [K] (type) $N\rm _{meth}$[cm-2]
Population $K_{{\rm u}}=0 (A)$ $145\pm12$ (rot) $(2.2\pm0.5)\times 10^{14}$
diagram $K_{{\rm u}}=0 (E)$ $120\pm8$ (rot) $(1.4\pm0.3)\times 10^{14}$
LTE model Envelope 40 (exc) $2\times 10^{14}$
input Hot core 120 (exc) $6\times 10^{16}$
LTE simu- $K_{{\rm u}}=0 (A)$ 164 (rot) $ 1.4\times 10^{14}$
lated obs. $K_{{\rm u}}=0 (E)$ 168 (rot) $ 1.7\times 10^{14}$

Notes. From the top: the rotational temperatures and methanol column densities derived from the observed population diagram; the input excitation temperatures and column densities of the LTE model; the rotational temperatures and column densities derived from the modelled population diagram.
