Titles: PMTE ============= Contact: N. West, Oxford. Revision History:- ================ 2.09 N. West First version. Titles Files ------------ pmt_eff_asym.dat Verification ------------ Description ----------- This bank contains the data on the PMT efficiency asymmetry. It is ONLY to be used to study the effects non-uniform PMT performance on the off-line analysis code. PMTs within the selected Z band have their hit efficiencies reduced by the reduction factor specified. Photons that are affected are lost, they are not bounced. All 3 pmt models (black disk, grey disk and 3d) are affected. !!! IT MUST NOT BE USED FOR PRODUCTION WORK !!! Use the command file sys_tube_asym.cmd to set the PMTE bank to the standard setting.
