- New diagnostic plotting tool `Calibration.tofpd..diagnostics.plot2d` which adds markers for expected peak positions
- New diagnostic plotting tool `Calibration.tofpd.diagnostics.difc_plot2d` which plots the change in DIFC between two instrument calibrations.
- New diagnostic plotting tool `Calibration.tofpd.diagnostics.plot_peakd` which plots the d-spacing relative strain of peak positions.
- New diagnostic plotting tool `Calibration.tofpd.diagnostics.plot_corr` which plots the Pearson correlation coefficient for time-of-flight and d-spacing for each detector.
