Notes. We select spectra with at least 2 consecutive channels deviating from 3σ from the continuum level. We keep positive and negative signals at each stage in order to have an estimate of the noise level. We provide the number of pixels and the number of core clumps derived. Only core clumps with at least 3 adjacent pixels are kept for subsequent analysis. The approximated mean flux is the mean value of the sums of detected pixels fluxes of all core clumps.
