This code is a simple implementation of Eq. (5) of "Modified Law of Corresponding States for Real Gases" by Su (1946) to generate a curve for a given T/T_cr to find the compressibility factor mu (or Z in some references, mu=Z=PV/RT).
The mapping is a little strange so you may need a lot of points to build the curve.
