Titles: PCAS: PCA Summary ========================= Contact: C. Kyba, Penn Revision History:- ================ 5.00 C. Kyba First version. Titles Files ------------ mpca_data.dat Verification ------------ Description ----------- This bank contains summary information for a single-photon PCA run. The data is used by the MPC processor to generate the Multiphoton PCA walk distribution. Data Words ---------- Data types: B(bit), I, F, D(double), H(hollerith 4 char) Word Type Mnemonic [symbolic command] Description ---- ---- -------- ------------------------------- 1 I KPCAS_NUM_TUBES Number of tubes listed in the file 2 I KPCAS_WORDS_PER_LINE Number of data words per tube 3..5 I Spare 6..10 F Spare 11..N F There are currently eight entries in the titles file for each data point, see the notes below. Notes ----- 1) The data is stored as a repeating table of floating point numbers. The first word of actual data is located at (KPCAS_STATUS_WORDS+1). Mnemonics have been set up to assist in reading the data. Assume that you are looking at data for the i'th PMT. The data is then stored in words: KPCAS_STATUS_WORDS+(i*KPCAS_WORDS_PER_LINE)+... +1 F KPCAS_TUBE Snoman PMT number +2 F KPCAS_HITS Number of times tube was hit during PCA run +3 F KPCAS_QHS Average QHS of PMT +4 F KPCAS_TAC Average TAC of PMT +5 F KPCAS_POS_X X position of PMT +6 F KPCAS_POS_Y Y position of PMT +7 F KPCAS_POS_Z Z position of PMT +8 F KPCAS_OCC Occupancy of PMT during PCA run
