-This is just a little help to tell the user how big the OSCILLATION_RANGE can be without producing overlap, but it does not take the crystal's mosaicity into account, so one has to subtract the mosaicity (0.1° for good crystals, higher for normal to bad ones). Please note that the resulting value is just the '''maximum value''', ''not'' the '''optimal value'''! A '''good value''', in terms of signal-to-noise ratio, is 0.25-0.5° for CCD detectors, and around 0.1° for the Pilatus. The '''optimal value''' is the ''minimum'' of the '''maximum value''' and the '''good value'''.
+This is just a little help to tell the user how big the OSCILLATION_RANGE can be without producing overlap. The maximum oscillation range is less than that given by the table, since the crystal mosaicity has to be subtracted from the table value. Please see [[Editing Choice of OSCILLATION RANGE]].
