PeakHKLErrors

.. index:: PeakHKLErrors

Description

This function calculates, for each peak, its h, k, and l offsets from an integer using goniometer settings and/or tilt and sample offsets from the parameters.

The original PeaksWorkspace is unchanged.

Outputs

The PeaksWorkspace is NOT changed.

The argument out in function1D has ,for each peak, the h,k, and l offsets from an integer using the current parameter values.

.. attributes::

   OptRuns;;;A list of run numbers whose sample orientations are to be optimized. The list is separated by ``/``
   PeakWorkspaceName;;;The name of the PeaksWorkspace in the AnalysisDataService


.. properties::
  1. SampleXOffset- XOffset of Goniometer center from instrument center in meters
  2. SampleYOffset- YOffset of Goniometer center from instrument center in meters
  3. SampleZOffset- YOffset of Goniometer center from instrument center in meters
  4. GonRotx- For Goniometer tilt. Rotation about x-axis in degrees where Tilt = Rotx(GonRotx)*Roty(GonRoty)*Rotz(GonRotz)
  5. GonRoty- For Goniometer tilt. Rotation about y-axis
  6. GonRotz- For Goniometer tilt. Rotation about z-axis( done 1st AFTER phi-chi-omega rotations)
  7. chixxx - xxx is a run number from OptRuns. This is the chi angle in degrees that will be used for that run( before tilting)
  8. phixxx - xxx is a run number from OptRuns. This is the phi angle in degrees that will be used for that run
  9. omegaxxx - xxx is a run number from OptRuns. This is the omega angle in degrees that will be used for that run

Note

When used in fitting, some or all of the first 6 parameters could be tied to zero.
