THE REST OF THE FILM (DATA SET 2) WAS AUTOMATICALLY SCANNED AND WE HAVE COMBINED A 9 PCT ANGLE DEPENDENT EFFICIENCY UNCERTAINTY WITH THE GIVEN STATISTICALERRORS AT THESE 8 MOMENTA. /// COMMENTS ON MODIFICATIONS TO LOVELACE71 COMPILATION BY KELLY -- LOVELACE71 HAS PRELIMINARY DATA (ID=ANTHON68).

在2.15至6.0 GeV/c的11个动量点处，负π介子-质子（π⁻p）微分截面（Differential Cross Section, DCS）在180度附近的分布。该实验在ZGS（零梯度同步加速器，Zero Gradient Synchrotron）上使用单臂光学火花室π介子谱仪完成。
动量为2.15、2.5和2.8 GeV/c的数据（数据集1）采用手动数字化仪进行测量，本数据集将5%的角度相关效率不确定度、2%的角度相关本底扣除不确定度与给定的统计误差进行了合并。
其余8个动量点对应的胶片（数据集2）采用自动扫描方式处理，本数据集将9%的角度相关效率不确定度与给定的统计误差进行了合并。
