Description
Just needs the definition of an appropriate shape as input to the MaskDetectorsByShape algorithm. They typically mask symmetrically on either side of the detector (so keep detectors where |angle|<phi and |angle-pi|<phi.

Needs the definition of appropriate shapes as input to the MaskDetectorsByShape algorithm.
First the easy one - masking by phi:
They typically mask symmetrically on either side of the detector (so keep detectors where |angle|<phi and |angle-pi|<phi).
Then the harder one:
On Sans-2d, after the sample comes first a circular aperture and then a set of jaws that create a rectangular opening. We need to project the masking due to these onto the detector banks (which can move). Although a first cut can treat the sample as a point, in reality it isn't and this should be taken into account.
