Compare the results of fitting gaussians to the brightness profiles in H alpha (HST) and F090W (JWST).
For the shell thickness we expect that the results should be roughly equal, but the dispersion in the relation gives us an estimate in the uncertainty in the thickness determinations
For the radius of the core, we expect that the HST results should be systematically larger due to the lower angular resolution.
For the brightnesses, it will be an interesting test of whether the emission in F090w is dominated by a process that is proportional to the ionized density squared in the same way as H alpha
