Notes. ID: label of the galaxy group members as shown in Fig. 1 (middle panel). MID: MUSE identifier (Inami et al. 2017; Bacon et al., in prep.). zsyst: systemic redshift as measured in Sect. 3.3. MUV: absolute UV magnitude close to 1500 Å restframe measured in the F336W HST band (Rafelski et al. 2015). log10(M*): logarithm of the stellar mass in M⊙. SFR: star formation rate in M⊙ yr−1. The parameters M* and SFR are based on SED fitting (Sect. 3.2). ΔvA: velocity offset from galaxy A in km s−1. ΔpA projected distance from galaxy A in kpc. q: projected axis ratio. PA: position angle in degree. The galaxy morphological parameters q and PA are from van der Wel et al. (2012) and measured in the WFC3/F105W band. EW2796: rest frame equivalent width of the Mg IIλ2796 line in Å as measured by pyplatefit (Bacon et al., in prep., Sect. 3.3).
