Notes. (a) We derived the signal-to-noise ratio (S/N) from the peak intensity Ipeak in units of σ = 0.28 mJy beam−1. (b) The flux densities were integrated inside the 5σ contour levels of the core. (c)The core mass was estimated from the flux density Sν using Eq. (1) for the clump-averaged temperature of Tgas = 55 K, see text. (d) The column density was estimated from the peak intensity Ipeak using Eq. (2). Uncertainties of the mass and column density estimates are discussed in Sects. 3.2 and 3.5. We stress that both quantities are only lower limits due to the flux filtering effect of ~ 65% (Beuther et al. 2018). (e)The second estimates for MMS1a and b were calculated from the core-averaged rotational temperature estimate from CH3CN (see Fig. 8).
