Hi Frank, older versions of XDSCONV, for datasets with weak high-resolution data, printed a long list starting with:
SUSPICIOUS REFLECTIONS NOT INCLUDED IN OUTPUT DATA SET (at most 100 are listed below) SUSPICIOUS REFLECTIONS NOT INCLUDED IN OUTPUT DATA SET (at most 100 are listed below) Type = 2 for centric, 1 for acentric reflections <Intensity> = Mean intensity in resolution shell Score = Intensity/Sigma - Sigma/(Type*<Intensity>) < -4 indicates a suspicious reflection h k l Type Intensity Sigma <Intensity> Score -11 5 -65 1 0.0000E+00 0.1184E+05 0.2316E+04 -5.11 -12 6 -64 1 0.0000E+00 0.1236E+05 0.2561E+04 -4.83 -13 12 -64 1 0.0000E+00 0.7067E+04 0.1745E+04 -4.05 -14 8 -64 1 0.0000E+00 0.1467E+05 0.3092E+04 -4.75 ... ... TOTAL NUMBER OF SUSPICIOUS REFLECTIONS REMOVED 115 For the latest version, I have re-worked the code such that the amplitude can still be obtained from the intensities in even weaker shells. (eventually some reflections may _still_ be rejected as suspicious but those are _much_ weaker than those rejected by previous versions) I hope this answers your question ... best, Kay
