CrystFEL's core symmetry module only knows about one setting for each unit cell.
You must use the same setting for now, but this will be improved in future
versions. The cell settings are the standard ones from the International
-Tables (2006). For monoclinic cells, the unique axis should be "b". For
-orthorhombic cells in point group mm2, the twofold axis should be along "c",
-i.e. no mirror perpendicular to "c". For tetragonal cells and hexagonal
-lattices, the unique axis should be "c".
