The fraction of the total population in the tails of the SNe timing and distance distributions for each variation (variations are outlined in Section 4.1). Scatter points indicate the f_{t > 44 Myr} (green), f_{D > 100 pc} (light blue), and f_{D > 500 pc} (slate blue) fractions. Note that 44 Myr is the assumed final core-collapse SN time in FIRE-3. Dotted lines and shaded regions show the fiducial value and a ±15% region around this value. The exact values for each variation are given in Table C1. An interactive version of this data is available in Figure 12.
