Notes. The density power-law index p is calculated according to Eq. (3). The core mass Mcore is calculated according to Eq. (5). The estimate of the chemical timescale τchem is explained in detail in Sect. 5.2. a(b) = a × 10b. Fit results for rin, rout, Tkin (rin), and q derived from either the H2CO or CH3CN radial temperature profiles (Fig. 4) are indicated by either a † or *, respectively.
