Specify parallax minimizer algorithm and bounds #628

Closed drewoldag closed 3 months ago

drewoldag commented 4 months ago

Currently we use the default scipy minimizer that is unbounded, which I believe to be using BFGS under the hood. It appears that if we specify reasonable bounds of heliocentric distance +/- 1.02, and the minimizer algo to be Nelder-Mead we should get about a 3-4x speed up.
