[http://www.mpimf-heidelberg.mpg.de/~kabsch/xds/html_doc/xds_parameters.html#SPACE_GROUP_NUMBER= SPACE_GROUP_NUMBER] - a mapping of space group names against their numbers is at the end of [[IDXREF.LP]].
[http://www.mpimf-heidelberg.mpg.de/~kabsch/xds/html_doc/xds_parameters.html#SPACE_GROUP_NUMBER= SPACE_GROUP_NUMBER] - a mapping of space group names against their numbers is near the end of [[IDXREF.LP]].


[http://www.mpimf-heidelberg.mpg.de/~kabsch/xds/html_doc/xds_parameters.html#UNIT_CELL_PARAMETERS= UNIT_CELL_PARAMETERS] - unit cell parameters need to respect the constraints of the Laue group, e.g. all angles must be exactly 90.0 for orthorhombic and tetragonal space groups, a and b must be equal for trigonal and tetragonal, and so on.
