Actually it says in the help file pretty explicitly that the CC models
must include a Q and U model.  But the whole model stuff is dubious
since a correct model will not contain the R-L phase difference that
is in the data and that is not part of the fitting.  The only model that
could work correctly is Q=U=zero.  It might be good to allow this
somehow but my mind is drawing a blank as to why we are using the
model since the D terms are found from RL and LR which are in various
combinations times the RR and LL fluxes, not the model fluxes or divided
fluxes.  Of course, PCAL allows > 1 calibrator and I guess they have to be on
the same scale....

I wish I was all the way over my recent illness - my brain still feels like mush.

LPCAL is the task designed I think for your use.

Eric
