THE FOLLOWING COMMENTS ARE TAKEN FROM THE PI N COMPILATION OF R.L. KELLY. THEY ARE THAT COMPILATION& apos;S COMPLETE SET OF COMMENTS FOR PAPERS RELATED TO THE SAME EXPERIMENT (DESIGNATED MARTIN74) AS THE CURRENT PAPER. (THE IDENTIFIER PRECEDING THE REFERENCE AND COMMENT FOR EACH PAPER IS FOR CROSS-REFERENCING WITHIN THESE COMMENTS ONLY AND DOES NOT NECESSARILY AGREE WITH THE SHORT CODE USED ELSEWHERE IN THE PRESENT COMPILATION.) /// MARTIN72 [J. F. MARTIN AND J. C. SLEEMAN,PRIV. COMM.,1972] -- PRELIMINARY VERSION OF SLEEMAN74 DATA. /// MARTIN72T [J. F. MARTIN,HEP/T/35(OXFORD THESIS),1972.] -- THESIS ON DATA ABOVE 1.4 GEV/C. /// SLEEMAN74 [J. C. SLEEMAN,PRIV. COMM.,1974.] -- DATA TAPE AND LISTING OF FINAL RESULTS OF THE EXPERIMENT. /// THRESHER74 [J. J. THRESHER,PRIV. COMM.,1974.] -- TWO ERRORS,STATISTICAL AND SYSTEMATIC,ARE RECORDED FOR EACH DATA POINT ON THE SLEEMAN74 DATA TAPE. DECIDING HOW TO USE THESE PROPERLY IN A FITTING PROGRAM IS NOT STRAIGHTFORWARD,PARTICULARLY SINCE (ACCORDING TO MARTIN72T AND THRESHER74) THE SYSTEMATIC ERRORS TEND TO BE SOMEWHAT CORRELATED BETWEEN DIFFERENT BINS. HOWEVER,THE CORRELATION BETWEEN THE STATISTICAL AND SYSTEMATIC ERROR IN A SINGLE BIN IS NOT LARGE,THE FIRST COMING MAINLY FROM EVENT COUNTING AND THE SECOND MAINLY FROM BACKGROUND ESTIMATION (SEE MARTIN72T). ON ADVICE OF THRESHER74 WE HAVE COMBINED THE STATISTICAL AND SYSTEMATIC ERRORS FOR EACH BIN IN QUADRATURE,AND HAVE NOT ATTEMPTED TO TAKE CORRELATIONS BETWEEN DIFFERENT BINS INTO ACCOUNT. /// MARTIN74 [J. F. MARTIN,RL-74-016,1974.] -- PREPRINT VERSION OF MARTIN75. NOT IDENTICAL TO MARTIN75. /// MARTIN75 [J. F. MARTIN,NP B89,253(1975)] -- PI+ P POL AT 68 MOMENTA BETWEEN 603 AND 2651 MEV/C. DONE AT NIMROD WITH LMN TARGET,SCINTILLATION COUNTER HODOSCOPES,AND CHERENKOV COUNTERS TO RESOLVE THE REGION OF KINEMATIC AMBIGUITY AND REDUCE BACKGROUND. THE NE IS RECORDED AS +/-6 PCT OVERALL AND +/-2 PCT RESIDUAL AT EACH MOMENTUM. THIS IS AN OVERSIMPLIFICATION AS DATA WERE TAKEN SIMULTANEOUSLY AT PAIRS OF MOMENTA SEPARATED BY ABOUT 1.9 PCT. THE RESIDUAL NE OF SUCH A PAIR IS 2 PCT,BUT THE NORMALIZATIONS FOR THE TWO MEMBERS OF THE PAIR ARE 100 PCT CORRELATED. THE MARTIN75 DATA ARE NOT THE SAME AS THE SLEEMAN74 DATA. /// COMMENTS ON MODIFICATIONS TO LOVELACE71 COMPILATION BY KELLY -- LOVELACE71 VERSION COMES FROM TWO PRELIMINARY VERSIONS OF THE DATA EARLIER THAN MARTIN72 (LOVELACE71IDS=BROWN70 AND SLEEMA71). MANY MAJOR DIFFERENCES. RUTHERFORD, POLARIZED TARGET.

/// MARTIN72 [J. F. MARTIN与J. C. SLEEMAN，私人通信，1972年] —— SLEEMAN74数据集的预发布版本。
/// MARTIN72T [J. F. MARTIN，HEP/T/35（牛津大学博士论文），1972年] —— 针对1.4 GeV/c以上能区数据的博士论文。
/// SLEEMAN74 [J. C. SLEEMAN，私人通信，1974年] —— 本实验最终结果的数据磁带与结果清单。
/// THRESHER74 [J. J. THRESHER，私人通信，1974年] —— SLEEMAN74数据磁带中的每个数据点均记录了统计误差与系统误差两类误差。在拟合程序中合理处理这两类误差并非易事，尤其根据MARTIN72T与THRESHER74的说明，不同能区箱间的系统误差存在一定相关性。但单个能区箱内统计误差与系统误差的相关性并不显著：前者主要源于事件计数，后者则主要来自本底估计（详见MARTIN72T）。根据THRESHER74的建议，我们已对每个能区箱的统计误差与系统误差进行方和根合成，且未考虑不同能区箱间的相关性。
/// MARTIN74 [J. F. MARTIN，RL-74-016，1974年] —— MARTIN75的预印本版本，与MARTIN75并不完全一致。
/// MARTIN75 [J. F. MARTIN，NP B89，253(1975)] —— 针对603至2651 MeV/c动量区间内68个动量点的π⁺p极化散射实验数据。实验在NIMROD装置上开展，采用LMN靶、闪烁计数器描迹仪与切伦科夫计数器，用于解决运动学歧义区域并压低本底。数据的归一化误差整体记为±6%，每个动量点的残余归一化误差为±2%。但该表述存在过度简化：实验同时采集了间距约1.9%的动量对数据，此类动量对的残余归一化误差为2%，但二者的归一化完全相关。MARTIN75数据集与SLEEMAN74数据集并不相同。
/// 凯利对LOVELACE71编译集的修改注释 —— LOVELACE71版本的数据源自早于MARTIN72的两个预发布版本（LOVELACE71IDS对应BROWN70与SLEEMA71），二者存在诸多显著差异。实验地点为卢瑟福实验室，采用极化靶。
