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] —— SLEEMAN74数据集的预发布版本。

THRESHER74 [J. J. THRESHER，私人通信，1974] —— SLEEMAN74数据磁带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类误差并非易事，尤其根据MARTIN72T与THRESHER74的描述，不同分箱间的系统误差存在一定相关性。不过，单个分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，我们对每个分箱的统计误差与系统误差采用方和根法合并，且未尝试考虑不同分箱间的相关性。

MARTIN74 [J. F. MARTIN，RL-74-016，1974] —— MARTIN75的预印本版本，与MARTIN75并不完全一致。
///
MARTIN75 [J. F. MARTIN，《核物理B辑》第89卷，第253页，1975] —— 603至2651 MeV/c动量区间内的68个π⁺-质子极化散射数据点。实验在NIMROD加速器上开展，采用LMN靶、闪烁计数器描迹仪与切伦科夫计数器，以解决运动学歧义并压低本底。数据整体归一化误差记为±6%，每个动量点的残余归一化误差为±2%。但该表述存在简化：实验实际同时采集了动量间隔约1.9%的成对数据，此类成对数据的残余归一化误差为2%，但每对数据的两个成员的归一化误差完全相关。MARTIN75数据集与SLEEMAN74数据集并不相同。

关于KELLY对LOVELACE71编译集的修订说明：LOVELACE71版本的数据取自早于MARTIN72的两个预发布版本（LOVELACE71IDS=BROWN70与SLEEMA71），与本编译集存在多处重大差异。该编译集的数据采集自卢瑟福实验室的极化靶实验。
