Warning X-corrections are from the old calibration New X & YZ correction are calculated after SCE correction There is no SCE correction infrastructure for showers

Summary

11

Overall everything looks OK A known problem is still there, when shower breaks into small showers. What about shower stitching? In some cases electrons are reconstructed as a track at the begging of the shower A little tune up for the shower it is necessary e.g. if there is a very small track followed by a big shower probably we can merged everything into a single shower SCE corrections? There is no calorimetry information from pandora and SCE corrections have been developed only for tracks
