Inelastic Bayes Fitting Testing#

Prerequisites

ResNorm tab#

Time required 3 - 5 minutes

  1. Go to Interfaces > Inelastic > Bayes fitting

  2. Go to the ResNorm tab

  3. With the vanadium combo box set to File click browse and select the file irs26173_graphite002_red from the Usage Data folder

  4. With the resolution combo box set to File click browse and select the file irs26173_graphite002_res from the Usage Data folder

  5. Click Run

  6. This should produce two workspaces with ResNorm and ResNorm_Fit suffixes

  7. Make sure that moving the black sliders in the plot will change the value of EMin and EMax

  8. Change the Preview Spectrum value and the plot should be updated with the corresponding workspace index

  9. Check that the maximum for Preview Spectrum is 9 (the last workspace index in the vanadium workspace)

  10. Check that when clicking Plot Current Preview, it will open a pop-up window with the current preview plot

  11. In the Output Options, select All and click Plot, it should open two plots suffixed with Intensity and Stretch

  12. Plot individual results by selecting other options, it should only open one plot with the selected result

Quasi Tab#

Time required 7 - 10 minutes (may vary depending on compute power of the test machine)

  1. Go to Interfaces > Inelastic > Bayes fitting

  2. Go to the Quasi tab

  3. Click on Manage Directories and set the default save directory to any location in your machine

  4. With the sample combo box set to File click browse and select the file irs26176_graphite002_red from the Usage Data folder

  5. With the resolution combo box set to File click browse and select the file irs26173_graphite002_res from the Usage Data folder

  6. Click Run. Keep an eye on the logs and progress bar on the main window to track the execution of the BayesQuasi2 algorithm, as this step may take some time to complete.

  7. This should produce three workspaces with Fit, Prob and Result suffixes

  8. Make sure that moving the black sliders in the plot will change the value of EMin and EMax

  9. Run the tab with different options in the Fit Options section

  10. Check that the maximum for Preview Spectrum is 9 (the last workspace index in the sample workspace)

  11. Check that when clicking Plot Current Preview, it will open a pop-up window with the current preview plot

  12. In the Output Options, select All and click Plot, it should open three plots with Prob, Amplitude and Gamma data. The Amplitude and Gamma plots will have a title ending in _Result.

  13. Plot individual results by selecting other options, it should only open one plot with the selected attribute

Stretch Tab#

Time required 3 - 5 minutes

  1. Go to Interfaces > Inelastic > Bayes fitting

  2. Go to the Stretch tab

  3. Click on Manage Directories and set the default save directory to any location in your machine

  4. With the sample combo box set to File click browse and select the file irs26176_graphite002_red from the Usage Data folder

  5. With the resolution combo box set to File click browse and select the file irs26173_graphite002_res from the Usage Data folder

  6. Set Beta and Sigma parameters to 5

  7. Click Run

  8. This should produce two workspaces with Stretch_Contour and Stretch_Fit suffixes

  9. Make sure that moving the black sliders in the plot will change the value of EMin and EMax

  10. Run the tab with different settings in the Fit Options section

  11. Check that the maximum for Preview Spectrum is 9 (the last workspace index in the sample workspace)

  12. Check that when clicking Plot Current Preview, it will open a pop-up window with the current preview plot

  13. In the Output Options, select All and click Plot, it should open two plots with FWHM(Sigma) and Beta data

  14. Plot individual results by selecting other options, it should only open one plot with the selected attribute

  15. Click Plot Contour to plot the stretch contour workspace
