3. Basic fitting for hyperfine beat (stage 1 bootstrap)#
For basic fitting, try a stage 1 style bootstrap. In this case, options are:
“basic” ignore the photoionization dynamics and just try fitting the beat to the \(l=4\), ROI=0 case, since it is already pretty close and may be assumed to be directly mapped here. See Basic fitting for hyperfine beat (stage 1 bootstrap).
“advanced” set (arbitrary) parameters per final state for the probe, and fit these plus the hyperfine beat model parameters. This should allow for a match to a single set of hyperfine parameters for all observables, and fulfil the stage 1 bootstrap criteria. See Advanced fitting for hyperfine beat (stage 1 bootstrap).
