"Table 33" 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 40 to 60 mrad and in the longitudinal range from 36 to 54cm, as a function of momentum. The normalization is per proton on target.

本数据集为从T2K复刻靶（T2K replica target）表面发射的带正电π介子的双微分产额（double differential yields），其测量区间的极角范围为40至60毫弧度（mrad）、纵向范围为36至54厘米，且该产额以动量为自变量。该产额按靶上每一个入射质子进行归一化。
