Notes. (†)Bold face shows the values from the best fit models. (a)The position of the dust continuum peak is at [−2.′′ 17;−2.′′ 76] relative to the phase centre position given in Sect. 2. (b)Measured in the synthesized beam of 0.″3 × 0.″17. (c)Brightness temperature of the continuum emission on the Rayleigh-Jeans scale. (d)Tkin correspondsto the gas temperature estimated from the CH3OH lines (Sect. 3.1). (e)Neglecting the effect of optical depth.
