Notes. (a) Effective radius Reff is defined as π Reff2 = A, where the A is the CH3OH emission area in which n(H2) can be reliably derived. (b) The largest radius (distance to the center) of n(H2) map derived by CH3OH; this is due to the irregular shape of the emission area. (c)The density profile of source G31 is better described by a two-component power-law form consisting of a shallow slope in the inner region followed by a steep slope of −5.22(0.045) in the outer region. (d) Upper limit is set to 400 K in the fit. (e)For sources G18, G19, G08a, G31, and G13, rin is a re-adjusted parameter based on SED calculation and comparison presented in Fig. 11 (temperature profile shown as blue lines in Fig. 20).
