Simulations data for the article "Chemical potential and surface free energy of a hard spherical particle in hard-sphere fluid over the full range of particle diameters" published in the Journal of Chemical Physics

The files (.mat - Matlab data format, .txt - ASCII format) contain simulation results for compressibility (z) of hard-sphere fluid at different packing fractions (eta) and excess chemical potential (mu_ex) of a test sphere of diameter sigma at different packing fractions (eta). z_CI and mu_ex_CI are the estimated 95% cofidence intervals (i.e., twice the estimated standard deviations) for the corresponding data values.该数据集包含不同填充率（η）和过剩化学势（μ_ex）下，直径为σ的测试球体在多种填充率下的硬球流体压缩率（z）的仿真结果。文件格式包括.mat（Matlab数据格式）和.txt（ASCII格式）。z_CI 和 mu_ex_CI 分别为对应数据值的95%置信区间估计值（即两倍估计标准差）。
