Top: Plane of effective radius (R${}_{\mathrm{e}}^{\mathrm{maj}}$) versus stellar mass coloured by SSP-equivalent population parameters measured within one effective radius. Dashed-black lines show constant velocity dispersion of 10, 20, 50, 100, 200, 300, 400, 500 km s⁻¹ from left to right, derived by the virial mass estimator M = 5R${}_{\mathrm{e}}^{\mathrm{maj}}$σ²/G. Bottom: General properties of the galaxy sample and the SFR as a function of the stellar mass (from SED fitting) for the sample galaxies. The dotted and dashed grey lines indicate the main sequence (MS) for an age of the Universe respectively of 12.4 Gyr (z = 0.1) and 6.8 Gyr (z = 0.8), given by Eq. (1) of Whitaker et al. (2012). We extrapolated the MS relations for galaxies with stellar mass M_⋆ ≤ 10^8.5 M_⊙. The grey background is the LOESS smoothed brightness of all objects brighter than 24 mag within the MAGIC and MUSE-Wide footprints.
