I have questions regarding how these values are determined.

Lp, Cp, are easily measured using any number of techniques.  But what 
about Ls or Cs?

Does Ls represent the "lumped' inductance of the secondary, measured (as 
above) between the base and top toroid?  I would bet this is the case 
but an not 100% sure.

But the really tricky one is Cs.  The only way I can see to determine 
this is by measuring the actual self resonant frequency of the secondary 
and toroid using a sig gen, 'scope and all that.  Then - you compute Cs 
via the frequency and Ls.

Any hints?  How are you folks determining these values?
