Fit ROI projection and use fit parameters as FOM

[ebadkamil]

Users suggested to have a direct measurement of pulse/beam width via fitting the ROI projection curve with Gaussian and using the fit parameters (sigma, peak-position) as FOM and then eventually use it to correlate with motor positions. This is essential for beam alignment. There was a suggestion from our side to use already existing STD as FOM but users believe it to be quite indirect way.

Hi all, bumping this feature request :D

SCS has a similar request, but they would also like to store and view the calculated values against different trains and pulses. I'm currently exploring the implementation of this feature with special-suite for the meantime, and I'm thinking how to store the values (e.g., whether to store inside a special-suite model object or to utilize a persistent DB, most likely Redis, and only retrieve the values on demand.)

Would you guys have any suggestions on how to implement this?

EDIT: Slept on it, and realized that Redis also uses RAM XD I tend to use model objects instead.
