Importance of orientations
With a radial diffraction experiment, you will look at texture and stresses, i.e. variations of diffraction intensities with orientations. Therefore, care should be taken in making sure that orientations are correct in MAUD.
In my experiments, I usually have my diffraction images in a way that the compression direction (the diamonds) correspond to
Setting orientations in MAUD
Before you finish your calibration, you should make sure that the orientations you use are correct. Since this can become very tricky, I wrote it out in a separate section: Define The Compression Direction. Make sure you have this right or you'll run into trouble later on.
