Ratio of star formation that takes place after 1 Gyr post perigalacticon compared to the same time in the isolation models. Carina-type dSphs are shown in orange, Sextans-type in green, Sculptor-type in blue and Fornax-type in red. Solid symbols represent those dSphs that retain over 80% of their stellar mass from the central 3 kpc, while open symbols represent dSphs that have lost over 20% of their stellar mass. The dSphs that have only undergone one perigalacticon passage are shown as circles, two passages as squares, and three passages as triangles. Fornax, located farther out than the other model dSphs shows the greatest resilience to quenching. Of the other model dSphs (which share the same orbits), there is a slight trend of decreasing resilience to quenching with increasing mass, particularly for models that approached perigalacticon at an early time.
