Diagram summarizing the procedures for generating the quiescent galaxies. ﹩{M}_{\star }﹩ is defined as ﹩\mathrm{log}(M/{M}_{\odot })﹩. Gray boxes indicate the empirical relationships, distributions, or data on which mock galaxy properties are based, and colored boxes indicate the mock galaxy property that is generated in that step. All quiescent mock galaxies are generated following these procedures.
