Notes. The masses are measured within a circle of 40′′ diameter around the peak position given in Table 1. The corresponding linear diameter is given. Δv is measured for the peak spectrum observed with the Effelsberg 100 m Telescope. Virial masses and virial parameter are given, depending on the density profile of the clump. For ISOSS23053, we chose the linewidth of the red component (see Sect. 4.1.3).
