Run_visalign diagnostic plots

[marshallmcdonnell]

Lots of diagnostics of individual pixel calibrations

Figure (a) Bankx_align.ps is after calibration, intensity as a function of pixel number and Q. This can be done with the existing color-fill-plot after AlignDetectors converts the data to d-spacing then an optional ConvertUnits to Q

Figure (b) Bankx_Dia220.ps fitted diamond 220 position relative to nominal as a function of pixel number. The found d-values for all peaks are in the _dspacing diagnostic workspace.

Figure (c) align.ps is histogram of the deviation from the nominal diamond 220 position over all non-masked pixel, Gaussian distribution shown for comparison

Figure (d) (generated by run_visalign.pro) Gaussian peakwidth of diamond 220 as a function of 2theta for each pixel

run_visalign also produces an ASCII file peakwidth_table.dat which is the content of the plot peakwidth.ps

• For the 2-D alignment plot (a), will just call color-fill plot from Mantid Framework (@quantumsteve is actively work on performance of this feature in Mantid). May work completely fine for NOMAD due to smaller number of pixels, could see in new Mantid Workbench.

• For the mean and std. dev. plot (b), can have it as an individual peak but right now, we have the "total" over all the peaks in the current Mantid implemenation. Need to write as a Mantid algorithm (Issue: not yet assigned). Need to bring in multiple instruments to decide the most beneficial information but do for a single peak initially.

NOTE: Want to do generally for any number of groups, not just the 6 normal banks (required if to be used by other diffractometers)

• For plot (c) with the distributions, this can carry over from the work in plot (b) above.

• For plot (d), this is already available from PDCalibration in the _resolution in DiagnosticsWorkspace output workspace group.

These exist in the calibration module, we just need to add to the UI.

@JeanBilheux we can discuss how to incorporate these into the GUI
