Spiral-to-S0 transformation probability as a function of the time from the galaxy’s entry into the cluster. The blue curves show the results of M23 for the spectrophotometric evolution of a sample of 15 field galaxies with typical log₁₀(M_★/M_⊙)≃10.5, assuming either instantaneous stripping (solid) or t_s = 0.5 Gyr (dashed). The solid black curve shows our fiducial model for log₁₀(M_★/M_⊙) = 10.5 and log₁₀(M_cl/M_⊙) = 14.7, with yellow shaded region showing its scatter given by the difference between the 84th and 16th percentiles. The dotted horizontal line with the grey band on top shows our fiducial p_max and its scatter.
