For this step in the calibration process, you enter the
values of momentum transfer q,
Bragg angle 2theta, or d-spacing d for the rings that you
will use for calibration. If you have read in a calibration file,
they will already be entered in editable boxes; if not, default
values will be entered.
For the calibration to work properly you need rings, not sharp peaks from
single crystals or fiber diffraction patterns, so your calibration material
should be a powder.
Type the parameter appropriate for each ring into one of the boxes labeled Q, 2Theta, or D.
