Inner-tabs of the MCS sub-tab in JBluIce. The loaded XDS_ASCII.HKL file is shown in the Reference Data tab, with corresponding cell parameters and space group. Test images from the current crystal are also listed in this tab. A multi-crystal strategy for maximum completeness for a new crystal, when combined with existing data, is shown in the XPLAN Strategy tab (`common' represents reflections common to new and old data as a percent of all measured data). The Merge Datasets tab can control datasets to include in scaling and resolution limits. The sample is thaumatin; each subset shown in the figure is a small wedge of data collected with a Rayonix MAR300 CCD (distance 300 mm, 1° angular width, 1 s exposure time) and processed in a primitive lattice in Laue group 4/mmm.
