For all the sweeps, processing stopped with | For all the sweeps, processing stopped with an [[Problems#IDXREF_ends_with_message|error message]] after the IDXREF step. By inspecting IDXREF.LP, one should make sure that everything works as it should, i.e. that a large percentage of reflections was actually indexed nicely: | ||

It may be possible to adjust some parameters (for COLSPOT) so that the error message does not occur, but it is not worth the effort. So we just change | |||

to | |||
JOBS=DEFPIX INTEGRATE CORRECT | |||
and run "xds_par" again. It completes after about 5 minutes on a fast machine, and we may inspect CORRECT.LP . | |||
