Notes. The first part shows the coordinates, and the second and third parts the 875 μm and the C18O(2–1) data, respectively. 875 μm clump parameters for 27.5′′ resolution. The table parameters are 875 μm peak and integrated fluxes Speak and Sint, effective linear clump radius from the clumpfind search reff, and calculated H2 column densities NH2 and gas masses M and Mpeak, derived from the total flux and peak flux, respectively. The C18O(2–1) part shows the peak and integrated line intensities Tpeak and , the peak velocities vpeak and line widths Δv, and the derived H2 column densities NH2 and virial gas masses Mvir.
