The challenges are
# partial data sets: each of the 100 data sets has only 3 frames of 1° oscillation
# partial data sets: each of the 100 data sets has only 3 good frames of 1° oscillation; later frames have strong radiation damage
# strong radiation damage: the crystals decay to about 1/2 within these 3 frames
# the crystals decay to about 1/2 within these 3 frames
# the b and c axes are the same length, but the crystals are orthorhombic. This makes it difficult to index them consistently - it is wrong to just merge them, because that yields a pseudo-tetragonal merged data set.
# the b and c axes are the same length, but the simulated crystals are orthorhombic. This makes it difficult to index them consistently - it is wrong to just merge them in a orthorhombic space group without resolving the indexing ambiguity, because that yields a pseudo-tetragonal twinned merged data set.
The solution is to use [[XSCALE]] for scaling, and [[xscale_isocluster]] for analysing the scaled data.
