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. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
