This plot takes each energy band from the dielectron gun simulation and integrates over a single |h| bin. This is done so that it can be fit to a line as to extrapolate the fractional resolution at pile up equal to 200. The |h| bin which was integrated over was from (1.0 < |h| < 1.5), the forward barrel. All of the energy bands with the exception of the first two remain within 5% resolution at pile up 200.
This data set follows the same model as above however takes the data points from the |h| range (2.0 < |h| < 2.5). Because this range is within the endcap the effect of Pile up is much larger. In this range all energy bands are above 5% resolution at pile up 200.
