INTEGRATE: Difference between revisions

* as a user, when your crystal-detector distance was chosen too low, or the reflections are very broad, or if the crystal has a high mosaicity (all of which result in many overlaps), you may try reducing MINPK down to some percentage between 75 (the default) and (say) 50. This will result in more completeness, ''but you should monitor the quality of the resulting data''. Conversely, if you raise MINPK above 75 you will discard more reflections, but the resulting dataset may be cleaner - again: ''check the statistics''. In particular, the latest versions of [[XDSSTAT]] prints out R_meas as a function of PEAK and intensity.

* this method degrades if the average profiles cannot be completey formed, as the scaling-up relies on their accuracy. This may happen if the reflections are too close in x,y and, at the same time, the mosaicity is high (such that no lunes exist, with edges that help constructing the average profiles). ''It is therefore useful to check the printed profiles in INTEGRATE.LP''. Again, the latest versions of [[XDSSTAT]] help to find the best compromise between data quality and completeness.
