Titles: PMTT ============= Contact: D. Wark, Oxford. Titles Files ------------ pmt_response.dat Verification ------------ Description ----------- This bank contains the data on the PMT timing and noise performance. Data Words ---------- Fixed length Database Header. See titles_dbhdr.html **For PMTT 1 (Information generic to all models) This bank is mapped into common Line Variable [Symbolic Command] Description ---- -------- ------------------------------ 1 T_TRANSIT Average transit time accross tube 2 TJITT Variance of the transit time spread distribution (ns) See warning. 3 TNOIS [pmt_nois_rate] Mean PMT noise rate in Hz. Warning ======= TJITT is no longer used in the simulation of the PMT response, since that is now represented by a skewed Gaussian function. Still, we require to assume something for fitters in order to compute a chi-squared, so TJITT has been retained for that purpose, as an "equivalent symmetric gaussian" of the current model.
