The current polynomial fits in the color analysis use numpy.polyfit, which performs a regression on the vertical offsets from the polynomial. A regression on the orthogonal distance to the fit is preferable (and required for nearly-vertical distributions). This ticket is to implement an Orthogonal Distance Regression using “odr” uses the scipy.odr module (the numpy.polyfit fit will be retained as it serves as an initial guess for the "odr" fit).
The work here will likely be done as part of the
DM-13154 ticket (as plotting limits and refinements may require adjustments as a result of this work).
Yusra AlSayyad, I just want to double check that you are satisfied that the work of this ticket was indeed completed as part of
DM-13154 and, as such, can be closed out.

The work of this ticket has been done on the
DM-13154ticket branch, so should be included in its review.
