"Table 47" of "Measurements of $\pi^{\pm}$, $K^{\pm}$ and proton yields from the surface of the T2K replica target for incoming 31 GeV/c protons with the NA61/SHINE spectrometer at the CERN SPS"

Double differential yiedls of positively charged pions emitted from the surface of the T2K replica target, in the polar angle range from 20 to 40 mrad and in the longitudinal range from 54 to 72cm, as a function of momentum. The normalization is per proton on target.

本数据集给出了从T2K复刻靶（T2K replica target）表面出射的带正电π介子的双微分产额（double differential yields），其测量极角范围为20至40毫弧度（mrad）、纵向范围为54至72厘米，该产额以动量为自变量，数据归一化方式为每入射至靶上的质子。
