Testing the effects of ring location on the methodology for a simulated galaxy. From left to right we show cases where the ring used to reconstruct the representative SFH of the underlying MD is placed at larger radii, in a case where the model has a negative age gradient in the underlying MD. The top rows show the locations of the rings with respect to the ND region, and the bottom panels show the SFHs. We see that when the ring is placed at larger radii, the representative SFH of the MD does not fully match the ND region at the oldest ages.
