Thomas,

Texeraux uses a Foucault test to measure the primary for Cassegrain series
telescoes.  If I remember right, he just does the normal "tex" analysis,
but uses -b*hm/R2 instead of hm/R2, where b is the "something" constant. (b
= -1 for a parabola).   I don't have it in front of me, but the equation is
in Texeraux.

He does the entire calculation including the transverse abberation.  I
don't see why you couldn't apply this analysis to any hyperbola, and use
the ± values from the Millies-LaCroix analysis to scale the TA.
