You found it! XDS.INP needs ROTATION_AXIS=-1 0 0
with this setting, IDXREF indexes more than half of the reflections: REFINED VALUES OF DIFFRACTION PARAMETERS DERIVED FROM 10956 INDEXED SPOTS REFINED PARAMETERS: AXIS BEAM ORIENTATION CELL STANDARD DEVIATION OF SPOT POSITION (PIXELS) 0.60 STANDARD DEVIATION OF SPINDLE POSITION (DEGREES) 0.15 I assume this is beamline BL17B1 from the Taiwanese NSRRC synchrotron, right? Why oh why do they rotate the spindle this way?
