:the default is "20.0 0.0" but it would be good to change this to sensible values for your data set, e.g. 50.0 for the lower resolution limit and the limiting resolution, where the average signal-to-noise ratio drops below 1, for the upper limit (the latter number could be obtained from [[CORRECT.LP]]).

:to exclude ice rings. Whether ice rings are a problem should be obvious by looking at frames, FRAME.pck and the "alien" statistics at the end of [[CORRECT.LP]]. Please note that there are five more "high-resolution" ice ring resolution ranges (given at the end of [[CORRECT.LP]]), in addition to the five ranges already supplied in templates of XDS.INP.
:to exclude reflections in [[Ice_rings|ice rings]] ([[CORRECT]] step). Whether [[Ice_rings|ice rings]] are a problem should be obvious by looking at individual frames (often later frames are affected more than earlier ones), FRAME.pck and the "alien" statistics at the end of [[CORRECT.LP]]. Please note that there are five more "high-resolution" ice ring resolution ranges (given at the end of [[CORRECT.LP]], and in the [[Wishlist]]), in addition to the five ranges already supplied in templates of XDS.INP.
