Stellar-to-halo mass ratios (grey and red solid curves) of dwarf galaxies of various categories at z = 0 based on their GC numbers versus models (various techniques). Grey curves represent a compilation of the SHMRs as presented in Behroozi et al. 2019. The shaded area around these SHMRs correspond to 0.25 dex uncertainty for the SHMR relations. The shown SHMR at these mass regimes is an extrapolation of the SHMR obtained for the more massive galaxies. The red solid line and the shaded area around it (in panels on the left) show the SHMR relation for low-mass galaxies (at z = 0) in Zaritsky & Behroozi 2023 and its uncertainties (0.31 dex). The shaded area around dashed curves represents the uncertainties in M_h, converted from uncertainties in N_GC. These uncertainties are converted from uncertainties in N_GC as estimated in Sect. 4.3 (using bootstrapping) and shown in Figures 10 and 11. The shown uncertainties also include to overall uncertainties regarding the N_GC − M_h conversion, which is ±(2 × 10⁹ N_GC).
