Just sending along the answers to my question about the imosflm crystal
missets and mosaicity plot from Ethan Meritt and Harry Powell.


>Value of the parameter as a function of diffraction image number.
If the parameter didn't vary, it would show as a horizontal line.

phi(x), etc are the crystal orientation angles.
mosaicity is self-named.

Hi Hari

phi(x) phi(y) and phi(z) are the crystal missetting angles - how much the
apparent orientation differs from the calculated one from indexing.
Historically, with crystals mounted in capillaries, the crystal would often
really slide about, but these days (with cryocooled crystals held rigidly in
loops) they account for things like the rotation axis not ebing
perpendicular to the X-ray beam.

"Mosaic" should be self explanatory...
