Unit Cell Refinement - what is needed
Profiled peak positions (using a peak profile program)
UNIT Cell refinement program to perform the refinement
Useful to check the alignment of your diffractometer (don’t just rely on one Silicon or Quartz peak); perform a unit cell refinement on the entire 2-theta range supported by the diffractometer (e.g., 5 to 160 for many Bragg Brentano diffractometers)
