:minimumum pixel distance between spots. This setting results in an upper limit to the longest primitive cell axis that IDXREF would find, so SEPMIN should be less than X-RAY_WAVELENGTH*DETECTOR_DISTANCE/(longest_primitive_cell_axis*QX). The default is 6; for Pilatus data one might need to lower this to 4 or even 3, for long axes. | |||

:should be half of SEPMIN (or less). This should be an integral value, so for Pilatus one should use 2 or even 1. | |||
