Notes. Column (1) gives the galaxy identification; Col. (2) reports the semi-major axis R₃₀ i.e., the extension of the galaxy at μ_FUV.CaF2 = 30 mag arcsec⁻² measured along the FUV.CaF2 luminosity profile. Correspondingly Col. (3) provides R_26.5, the radius at 26.5 mag arcesec⁻², derived from the I-band by CGS (Ho et al. 2011); Cols. (4) and (5) give R_29g and R_28r, the semi-major axis the galaxy luminosity profile at 29 and 28 mag arcesec⁻² in the g- and r-bands, respectively. ⁽¹⁾Data are from Ram2021; ⁽²⁾The radius for PGC 75125 refers to μ_FUV.CaF2 = 29 mag arcsec⁻²; ⁽³⁾Data are from Cattapan et al. (2019); ⁽⁴⁾Data are from Ragusa et al. (in prep.). ^( * )The radii for IC 2038 and IC 2039 in Cols. (5) and (6) refer to μ_g = 25 mag arcsec⁻² and μ_r = 24 mag arcsec⁻², respectively.
