The Vega equation of state for hard (biaxial) ellipsoids is given by (Ref. 1 Eq. 20):

where is the compressibility factor and is the volume fraction, given by where is the number density. The virial coefficients are given by the fits


and

where

,


and

where is the volume, , the surface area, and the mean radius of curvature.

For see B_2 for any hard convex body.
