Note: the pixel numbering in VIEW goes from 0 to NX-1 (similar for y), whereas XDS using a numbering of 1 to NX (NY). Thus, if you find out a position on the detector (e.g. the direct beam) by using VIEW, you should add 1 in both x and y if you want to put the numbers into [[XDS.INP]]. | Note: the pixel numbering in VIEW goes from 0 to NX-1 (similar for y), whereas XDS using a numbering of 1 to NX (NY).

The Logo of this wiki (upper left) shows part of FRAME.pck as visualized with VIEW. Here we see the "pixel labelling method" of [[XDS]] at work: the thin lines around the reflections demarcate the limits of the integration box. The size of the integration area is calculated from BEAM_DIVERGENCE, but in case two such integration areas overlap, then each pixel in the overlap region is assigned to the nearest reflection in reciprocal space. | |||
Empty integration areas belong to weak reflections. Reflections without integration area are partial reflections, whose center is on an adjacent frame. | |||
