Merging the detector images taken at different angular positions

[azkhadiev]

First of all thank you very much for this nice package. Would it be possible to use the detector images taken at different positions for generating the reciprocal space? I was thinking of something similar to MultiGeometry class implemented in PyFAI.

Thank you in advance!

This is to an extent possible at the moment. If you specify a large Q space for the transformation, covering all detector positions, then you can combine together all the arrays for the detector. This does however require equal sampling of all spots in reciprocal space otherwise the intensity at each position can be over or under contributed when the arrays are combined. For a simple rotating detector this just means equally spaced detector angles, and ensuring that for each location in your final array you are summing from the same number of images, requiring your first detector position to be below the first useful data. In other words if your detector has a 'angular height' of 2θ = 10°, then for 2θ = 0-20° data must be collected at regular intervals from 2θ = -5 - 25°. However agree it would be great to have the MultiGeometry class implemented in pygix! Or alternatively if the functionality of pygix was merged into pyFAI.
