Right now lots of things are hard-coded.
These can be constructed from the derivatives you have.
Then run it into scipy.optimize
BFGS and see if that crushes.
the code is currently brittle here.

Spline will probably go crazy near the edges of the fitted region - how do we prevent that?
Let's define
\xi \equiv \ln \sqrt{ \frac{v+c}{v-c} }
and fit for \xi
not \beta
. With this definition (or maybe with the +
and -
reversed),
x' = x - \xi
Scale parameters should absorb the varying flux levels so that a_ms just fit the shape of continuum & spectral features.
This will give us some idea whether we have a chance of getting anything.
