Someone else (forget who), showed to my satisfaction at least, that there
was no need for anything beyond C0 for cal kits. He checked 3 kits I own
* 85054B 18 GHz N
* 85052B 26.5 GHz 3.5 mm
* 85050B 18 GHz APC7.
He used some Octave code which showed that for those cal kits at least,
there was no point having any more than C0, as the effects of C1, C2 and C3
are smaller than the uncertainties of the calibration kits.
I should have added, that there is possibly some point in including C0, C1,
C2 and C3 on homemade cal kits, but not inductance coefficients.
