Theoretical light curves of a few BL Her models in the Rubin-LSST filters computed using convection parameter set A. The input stellar parameters of the corresponding models are included in the format (Z, M/ M_⊙, L/L_⊙, T_eff) in each sub-plot. The increasing stellar luminosity (L/L_⊙) are plotted from the bottom to the top panels, while the increasing effective temperature values (T_eff) are displayed from the right to the left panels.
