xx_EH Column Output Remains Zero in hst File Upon ‘mks’ Transformation

[zzlphysics]

Upon employing the “mks” transformation, it has been observed that the xx_EH column within the hst file consistently yields an output of zero values.
Maybe the code snippet located at https://github.com/AFD-Illinois/kharma/blob/9968b2f21d6edcba9ce2d650a948412e86ddd85e/kharma/kharma.cpp#L219 should be revised to the following for potential resolution?
const GReal x1min = (nx1 * x1hor / 5.0 - x1max) / (-1. + nx1 / 5.0);
