Properties of NOEMA CO(1–0) compact clumps identified with PYCPROPS. Cyan stars mark clumps associated with the SE filament, and black circles mark the other clumps in the field. Upper left: radius–velocity dispersion relation, compared with the Milky Way disk relation (P. M. Solomon et al. 1987), the M33 disk-wide relation (K. Muraoka et al. 2023), and the CMZ fit (T. Oka et al. 1998); dashed–dotted lines show fits with a fixed R^1/2 slope to the two NOEMA subsamples. Upper right: radius–surface density relation. Lower left: surface density–velocity dispersion relation. Lower right: size–line width–surface density relation, with lines corresponding to virial parameters of 1, 2, and 10.
