After the best calibration parameters (wavelength, q-range, tilt, etc.) have been determined, they can be saved in a file for subsequent use. In the Calibration window this is done by using the Save Parameters button to save and the Retrieve Parameters button to retrieve; when running the Least-Squares Calibration Wizard the user is also given the opportunity to save the obtained parameters. Previously saved parameters can be retrieved in Batch mode using the "RETRIEVEINSTRUMENTPARAMETERS" command.
If you have somehow gotten the parameters into a strange and unphysical combination (this happens only occasionally restore "factory settings" by clicking Restore Defaults.
