Left: distribution of the spatial coverage of the F3D MUSE data for ETGs (solid line) and LTGs (dashed line) in units of effective radius, as measured along the major axis. Right: spatial coverage of the F3D ETGs (circles) and LTGs (crosses) as a function of the total stellar mass. The long-dashed and dash-dotted lines correspond to the average spatial coverage from the long-slit data of Bedregal et al. (2006) and integral-field data of Scott et al. (2014), respectively. The adopted values of R_e for the comparison with literature are given in Table C.1.
