A fourth type of interactive colour-coded reciprocal-lattice display has been added when the input data are given as an unmerged XDS_ASCII.HKL file (not MTZ format).  The left-most scene then shows the value of the CORR statistic produced by XDS (item 11 in the file), i.e. for each reflection, the correlation coefficient between the observed reflection profile and the predicted profile that was used to integrate it.
The profile correlation plot gives a primary diagnostic of problems at the integration stage, as a mismatch of profiles could result from shortcomings in the sample (e.g. a cracked crystal) or in the profile estimation method (e.g. too coarse a partitioning of the detector surface).  As the profile correlation is given on a per-reflection basis, it is a more sensitive indication of such problems than the loss in <I /σ(I)> that it causes, since the latter quantity is a local average.
