Simple Background Quantification

[Nick Draper]

Simple background energy model can be fitted for an MDWorkspace. Other models and foreground models will be done under new ticket.

[Janik Zikovsky]

(In [6527]) Refs #1644: Added the NOT and PLUS operators for filters. Added full test.

[Janik Zikovsky]

Oops - that last comment is supposed to be on ticket #1664. Please ignore for this ticket.

[Ronald Fowler]

(In [7677]) Initial attempt at simple background calculation based on the IMDWorkspace with test MDPoint and MDCell data. Does not yet check that final output is correct, only that input is as expected. re #1644

[Nick Draper]

Bulk move of tickets to iteration 27, if your ticket is essential for Iteration 26 then move it back.

[Ronald Fowler]

(In [9000]) Updated simple background functions for tobyfit in SimulateMDD.cpp and included some of the framework for simulation of foreground scattering in TobyFitSimulate.cpp. re #1644

[Nick Draper]

Bulk move of tickets at the end of iteration 27

[Ronald Fowler]

(In [9560]) Minor updates re #1644 to remove unit test failure Added class for storing run parameters needed for Tobyfit operation, no tests yet.

[Ronald Fowler]

(In [10565]) Added a simple background function depending on energy re #1644 . Tests GenericFit with a simple MDWorkspace. Also added runId method to MDPoint and unit test for simple class RunParam.

[Ronald Fowler]

(In [10647]) Added additional point to test data in QuadEnBackgroundTest.h so that fit has DOF=1 rather than DOF=0, which was unrealistic and causes problems for LM. re #1644

[Ronald Fowler]

(In [10690]) Added a simple foreground function for cobalt. Does not include integration yet, just framework for defining foreground functions. re #1644 .

[Nick Draper]

Bulk move of tickets at the end of iteration 28

[Ronald Fowler]

(In [11267]) Minor changes towards a foreground integration scheme. re #1644 .

[Nick Draper]

"New" tickets moved at the code freeze of iteration 29

[Nick Draper]

Bulk move of tickets to iteration 31 at the iteration 30 code freeze

Refs #1644 - updating files to take into account new IMDWorkspace

Mainly updates to the QuadEnBackgroundTest.h file to set up a new IMDWorkspace to test. Not yet complete.

Changeset: d9637723420edfbc9c6615ecdb419c247363dbef

Adding MDEvent test workspace to SimulateMDDTest.h re #1644

Changeset: 4c7bde120d0af4ddf5c0f5239ecb675e106e8e86

[Ronald Fowler]

More changes to allow MDEvent workspace to work with simple background

re #1644. Currently only works for an event workspace where "events" are really detector pixels. Small update to MDEventsTestHelper.h to add non-Lean MDEvents

Changeset: 9fb24531b781f6e06981f77a2fc8478f7757fd66

[Ronald Fowler]

More updates for background fitting to MDEevents workspaces

Changed MDAlgorithms/CMakeLists.txt to re-include QuadEnBackground test and to include needed references to the curve fitting library to build this. QuadEnBackgroundTest.h changed to use MDEventWorkspace and remove old code. QuadEnBackground.cpp minor changes. Note this uses normalization by number of events, while fitting currently works on volume normalization. Latter needs changing. Re #1644

Updates to background fit testing re #1644

Updated QuadEnBackgroundTest to check simple use of CompositeFunctionMD. Also updated Iterators to add methods getSignal() and getError() to get the sum of these values without volume normalization. This is needed in Tobyfit for normalization by the number of detector bins contributing to the signal, i.e. getSignal()/getNumEvents().

Moved to iteration 33 at iteration 32 code freeze

[Janik Zikovsky]

Refs #1644: IFunctionMD made to use IMDIterator->getDataSize() ...

instead of relying on dimensions, since that implies regular binning. Took out MDEventsTestHelper method that were added to make it work anyway. WARNING: It looks like the copy of the data made by the IFunctionMD::setWorkspace() method is of it->getNormalizedSignal(); whereas the QuadEnBackground function uses the # of events normalization. This will cause a problem. Commented out a test that was now failing.

[Janik Zikovsky]

The scope of the work in the ticket, iterator with number of events, is complete. However, remaining issue pointed out in ticket #4468.
