Feature: fit only some sections to magnitude, or separate weights by mag/phase
Jenne:
Kara is trying a method with PRCL to replace the low frequency data with her own hand-generated measurement data. If it were possible to tell IIRrational that in some area it needs to only fit the magnitude, and we don't care about the phase, this would probably be an easy way to solve our problems, but I don't know if we can do that. Is there any way we can tell IIRrational to not use the phase as part of the fitting metrics?
