"Table 252" 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 protons emitted from the surface of the T2K replica target, in the polar angle range from 220 to 260 mrad and in the longitudinal range from 54 to 72cm, as a function of momentum. The normalization is per proton on target.

T2K复现靶表面发射质子的双微分产额，其极角范围为220至260毫弧度（mrad），纵向范围为54至72厘米，且为动量的函数。归一化方式为每入射质子。
