Comparison of Electron and MIP Calibrations
This page compares the new tower calibration performed using only electron E/p to the calibration using last year's algorithm. The two calibrations are found to be consistent within 120 MeV in E_T.
I've also attached the tower-by-tower plots of electron E/p so you can see the results for yourself. I'll write up a more complete description of the calibration algorithm shortly.
