Distribution of surface brightness and color values of our galaxies at R=R_edge. The surface brightness values have been corrected for Galactic extinction using A_NUV = 7.95E(B−V) and A_FUV = 8.06E(B−V) (see Bianchi et al. 2017) and for their respective inclinations using Eq. (2) from Trujillo et al. (2020) and assuming a ratio of scale height to scale length of z₀/h = 0.12. The rightmost panel shows the distribution of the edge radius in the UV bands in kiloparsecs.
