Add version of FM90 using B3 instead of C3 #201

Closed karllark closed 9 months ago

karllark commented 9 months ago

The FM90 formulation for the bump "strength" is C3. This is not the amplitude. That is C3/gamma^2. For ease of interpretation and fitting, it is better to use the bump amplitude B3 = C3/gamma^2. B3 is then the height of the 2175 A bump. And B3 is not strongly correlated with gamma in the fitting, unlike C3.
