Quiescent fraction f_Q as a function of stellar mass and the infall proxy d_R for the full galaxy sample. The bottom-left panel shows f_Q in the log M_★/M_⊙ − d_R plane with colors indicating f_Q. The top and right panels show the corresponding one-dimensional trends of f_Q as a function of d_R and log M_★/M_⊙, respectively. The bin sizes are 0.25 in both Δd_R and Δlog M_★/M_⊙. The f_Q values in each bin are indicated by solid horizontal lines and the shaded squares show the 68% Wilson binomial confidence intervals for f_Q.
