Enable patch sensitivity for HFIR SANS

[Mathieu Doucet]

EQSANS has a way to create a sensitivity file where areas of the detector can be 'patched'. For instance, if the signal at the beam center is blocked, the user can mask that area and the sensitivity calculation will compute the average sensitivity along the tube corresponding to each masked pixel and assign that value them. The result is a sensitivity workspace that covers the whole detector.

We would like to enable that functionality for HFIR SANS.

To test:

• Start the HFIR reduction UI
• Enter a file in the sensitivity box on the Detector tab (check the apply sensitivity box first).
• Check the patch sensitivity box, then click the Patch button to draw a patch by using the mask tool.
• Click the Compute Sensitivity button.

• A workspace named "sensitivity" should be produced. Right click on it and select the option to show the detector. You should see the detector, and the areas that you masked should now be replaced by non-zero values. The values should be constant along the tubes, so you might see strips.

Hi Mathieu, please can you check this, it seems that the branch has not been fully merged to develop.

ERROR: Branch 'feature/10356_hfir_patch_sensitivity' has not been fully merged to develop, meaning it is not possible to know whether the code is valid on all environments.

Contact Mathieu Doucet on doucetm@… (or via skype) and ask them to merge the code to develop using 'git checkbuild' from their branch feature/10356_hfir_patch_sensitivity and let you know when it passes testing on the buildservers so you can start testing.
