2016-12-09New polarisation correctionThomas White
2016-11-10Fix 2theta calculation in locate_peak_on_panel()Thomas White
The "improved" version of this, added by 9b1374999 along with the new spot position calculation for out-of-plane panels, actually assumes that the reflection is at the exact Bragg condition. This is not a valid assumption here. The difference is small (<0.5 px), but made the prediction refinement gradients completely wrong.

2015-04-20Make panel assignments invariant during prediction- and post-refinementThomas White
Reflections appearing and disappearing are problematic when trying to do a least-squares refinement. Therefore, assume that reflections stay on panel and keep them under consideration even if their partialities go to zero (i.e. they drift off Bragg). This should stabilise both refinements, and simplifies quite a lot of code. Collateral "damage": the old "select_intersection()" is now gone.
