How the tables were made

The temperatures and pressures of each table were chosen by Simuveliq; no table was copied from a book. The values are computed by our own program (herramientas/termo/generar.py) with CoolProp; the calculator uses the same equation-of-state coefficients and was checked against CoolProp point by point.
