Best fit model parameters for the CH₃OCHO v = 0 and v_t = 1 transitions for the emission azimuthally averaged at different rings.

R	R	T_ex

0.22	1740	436±20	20^a
0.44	3480	343±29	12.6±0.8
0.66	5200	233±16	7.9±0.5
0.88	7000	182±11	4.0±0.2

Notes. ^(a)This value has been fixed to the value obtained by extrapolating a linear fit from the R = 0.′′44 and 0.′′ 66 rings. If both T_ex and are left as free parameters, the algorithm gives an unrealistic high excitation temperature of > 1000 K for the R = 0.′′22 ring.
