Model parameters
Note that the cross-section option (xseca) should not be enabled, because
it it does not affect the bound and resonant states, but can substantially
slow down the calculations.
Note
Once mcasopt has found a solution, you may wish to re-run MCAS with the cross-section option enabled.
