With a finite energy bandwidth each reflection is smeared RADIALLY by sigma_bw = bandwidth_sigma * R_px (R_px = distance from the beam centre, so large at high resolution): high-resolution spots become radial streaks. The isotropic per-shell Gaussian both mis-weights them and clips the streak tail on the fixed profile grid, losing intensity (biased low, noisy). When a bandwidth is set, fit each reflection with a per-reflection Gaussian elongated only along its radial direction - sigma^2_radial = sigma^2_intrinsic + sigma_bw^2, sigma^2_tangential = sigma^2_intrinsic - on a grid grown to hold the streak. Unlike an isotropic widening this adds no tangential background. It only engages where the smear exceeds the intrinsic spot (high resolution); low/mid resolution and monochromatic data (bandwidth 0, e.g. rotation) are untouched. On the HEWL serial-stills jet (with the background sigma-clip) this lifts the overall CC-vs-reference 52 -> 55% and the high-resolution I/sig (1.7 A 0.5 -> 1.4), recovering the 2.0-2.5 A band, with CC1/2 preserved (the per-shot noise the wider region adds is averaged out by the high serial multiplicity). Rotation ISa 19.1 unchanged. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
