Distribution of the physical properties of the PGCC objects with FQ = 1 (blue) and FQ = 2 (green). The coloured shaded regions provide an estimate of the impact of the individual uncertainties on the statistical distribution at a 1σ dispersion level around the mean value obtained from 10 000 MC realizations (see Sect. 6 for more details). The temperature distribution is shown for two temperature estimates, i.e., using a free emissivity spectral index β (solid line) or a fixed β = 2 (dot-dashed line). The distribution of the intrinsic size, after deconvolution, is shown on the top right panel in dot-dot-dot-dashed line. The distributions of the physical size, mass, mean density and luminosity of the clumps are provided for sources with reliable distance estimates (DIST_QUALITY=1 or 2). These distributions are also shown separately for sources at solar distances smaller or larger than 1 kpc from the Sun, in dashed and dotted lines, respectively.
