The flat faces ( also called facets ) of a euhedral crystal are oriented in a specific way relative to the underlying planes of relatively low Miller index.

For example, one study reports that high-index facets of platinum nanoparticles ( that is Miller indexes with large integers, such as Pt ( 730 ) ) provide a greater density of reactive sites for oxygen reduction than typical platinum nanoparticles.

This converts the hundreds of images containing the thousands of reflections into a single file, consisting of ( at the very least ) records of the Miller index of each reflection, and an intensity for each reflection ( at this state the file often also includes error estimates and measures of partiality ( what part of a given reflection was recorded on that image ) ).
