Notes. (1) COSMOS Group ID. (2) and (3) J2000 coordinates of the centers of the galaxy groups. (4) Exposure time per field. Exposure using adaptive optics are marked in bold. (5) Median redshift of the group. (6) MUSE PSF FWHM of the narrow band image around the observed wavelength of the [O II] doublet at the group redshift. (7) Number of galaxies (i) all: total in each group; (ii) SED: with SED fitting information (SFR and stellar mass); (iii) MS: on the main sequence of star-forming galaxies; (iv) KS: in the final kinematic sample. (8) Virial mass of the groups.

(a)

CGr32 has been observed within a mosaic of three adjacent MUSE fields having the same exposure time (1 h without and 3.35 h with adaptive optics). The three PSF FWHM values correspond to each field.

(b)

CGr84 and CGr84b are both observed in the same two adjacent MUSE fields. The two values of exposure times and of seeing correspond to each field.
