Calibration mtg on 6.8.2009 - shows the intercalibration coefficients for the 4 Dees separately. Dee4 coefficients are higher therefore Dee4 will have higher noise. NOTE, plot for B=0T. B-field will reduce VPT yield further and increase noise further - reduction due to B-field greater as go out in radius, since VPTs at greater angle to field.

POG/egamma-25May2009 Below, slides relating to Monte Carlo noise values from EE calibration constants. Higher noise in EE- than in EE+ due to lower yield VPTs in Dee4 (EE- F). The channel calibrations have been later improved (see 6.8.2009). These slides suggest that the MC has individual channel calibration coefficients in the code.
