Luminosity function of the NGC 2750 system compared with those of observed and simulated systems. Left: comparison with the observed systems studied by the ELVES survey (gray lines). Values for the NGC 2750 system are marked with a red line, with the dashed part indicating the values of the DGCs, while the shaded area accounts for the distance uncertainty. The blue line represents the median distribution of the ELVES survey, with the shaded areas being the 1, 2, and 3σ confidence intervals. The lower M_V limit coincides with the ELVES survey completeness limit of −9 mag (Carlsten et al. 2022). Right: comparison with the simulated systems selected from TNG50 (gray lines). Again, the green line represents the median distribution, with the shaded areas being the 1, 2, and 3σ intervals.
