This is the dataset presented in the article "Nanothermodynamic description and molecular simulation of a single-phase fluid in a slit pore" [1]. The columns from left to right are Slit pore height Normal pressure Standard deviation of the mean of the normal pressure Integral pressure Standard deviation of the mean of the integral pressure Surface tension Standard deviation of the mean of the surface tension Normal pressure from local fluid number density profile Standard deviation of the mean of the normal pressure from local fluid number density profile Fluid number density Standard deviation of the mean of the fluid number density Number of samples Zeroes Temperature Standard deviation of the mean of the temperature Potential energy Standard deviation of the mean of the potential energy Kinetic energy Standard deviation of the mean of the kinetic energy https://arxiv.org/abs/2012.00562
