Our implementation is using synonymous names for parameters compared to the paper by J.A. Wollmershauser, B. Clausen, and S.R. Agnew.
'xi_inf' and 'chi_inf' are not strictly "asymptotic values", but stresses that correspond to the back-extrapolation from the terminal linear hardening stage (characterized by 'h_inf_xi/chi').
All parameters are referenced back to their counterparts in the paper by J.A. Wollmershauser, B. Clausen, and S.R. Agnew.

this material was the initial motivation for adding fourth order
polynomials, but I could not find a reliable source for the graphs send
to damask@mpie.de . It seems that the CTE levels off for even higher
temperature which calls for a higher order polynomial

cryogenic temperatures are normally not of interest, avoid considering
the strongly curved region below 80K in the fit gives probably better
extrapolation properties for T>300K
