The hexagonal-ice ring FWHM measured on JUNGFRAU data (azimuthal radial background
profile) is ~0.06 q, so the exclusion half-width should be ~0.03; the previous 0.02
under-covered the strong low-res rings. On EP0117 with --detect-ice-rings this lifts
CC1/2 37->50%, and combined with --reject-outliers 3 (which down-weights the
radiation-damaged late frames) reaches ~94% (XDS 98.5%). Only active with
--detect-ice-rings, so default behaviour is unchanged.
