CU ACD have basically two calibration parameters for each channel (PMT), 6 in total - MIP peak position and pedestal (both - in ADC bins). Calibration parameters (pedestals, MIP peak positions and tiles light yield) for PS obtained in the 5 GeV pions runs on July 29, are given in the attachment. These parameters are preliminary and are subject for the revision. Please use them with caution.
Calibration parameters for SPS runs, obtained in 150 GeV proton runs 700001865-700001871 are given in table below. Explanation for the Tile 3 is given in the attachment "ACD_Tile_3_calibration.doc"
