leonarski_fandClaude Opus 4.8	7d1fb8db77	bragg integration: clarify that the trimmed background applies to stills too ... The background trimmed mean is gated on the beam (monochromatic vs broadband), not on the acquisition mode: a monochromatic still (zero bandwidth) already gets the trim by default, only broadband (non-zero bandwidth: pink-beam / DMM) data keep the high-side sigma-clip. The comments, the settings doc and the --background-trim help wrongly implied the trim was rotation-only / that stills keep the sigma-clip. Wording only; no behaviour change.

leonarski_fandClaude Opus 4.8	c3e877d5ec	bragg integration: trimmed-mean background, on by default for rotation ... The local Bragg background is the mean over the r2..r3 ring. That mean reads high because the contaminants that survive the signal-disk mask - neighbour- spot wings, tails, zingers - are one-sided (positive), so it over-subtracts. Since a weak intensity is a small difference of large numbers (I = S - nS*b), a per-pixel background bias is fractionally largest at the resolution edge, exactly where it hurts most. Replace the ring mean with a symmetric trimmed mean (sort the ring, drop the lowest and highest fraction f, average the rest), controlled by a new BraggIntegrationSettings field and the rugnux `--background-trim <f>` option (default f=0.10; 0 restores the plain mean). Default on for monochromatic (rotation) data; broadband (stills) keep their tuned high-side sigma-clip, so the base engine forces the trim to 0 there. Implemented in both the CPU engine and the GPU kernel (shared-memory bitonic sort per block, flat-mean fallback above BKG_TRIM_MAX ring pixels); the two agree. 25-crystal rotation battery (fixed SG/cell): <I/sigma> improved on every crystal (median +50%), ISa on 20/22, resolution-edge R_meas fell several-fold (e.g. lyso_ref 1.0 A 108%->43%). Last-shell CC1/2 is rescued where the plain mean had collapsed to noise (Thau_9 at ~2.0 A 3.8%->64%, ~0.5 A of resolution regained; cytC_10 0.2%->10%) at a small cost (1-3%) in already-clean shells - it flattens the CC1/2 fall-off rather than shifting it. Stills unchanged. Documented in CPU_DATA_ANALYSIS.md section 9.2. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>	2026-07-16 18:32:57 +02:00
leonarski_f	d6389e12da	v1.0.0-rc.156 (#66) ... This is an UNSTABLE release. It includes many experimental features, as well as many AI generated fixes. We recommend using rc.152 for production use. * jfjoch_process: Major rotation (rot3d) data processing overhaul - robust profile-fit integration, Cauchy-loss scaling with optional absorption surface, de-novo indexing and space-group/centering determination fixes, and merging statistics + ISa in the mmCIF output. * jfjoch_process: Add EXPERIMENTAL ice-ring detection (--detect-ice-rings) that excludes ice reflections from scaling. * Compression: Add BSHUF_ZSTD_RLE_HUFF, make compression size-aware (drop frames that don't fit rather than aborting), and add the jfjoch_recompress tool. * jfjoch_viewer: Report "Multiple lattices detected" and grey out "Analyze dataset" on a live connection. * jfjoch_broker: Write smargon chi/phi goniometer positions to NXmx; read sensor thickness/material from HDF5 metadata. * CI: Build Windows (CUDA and non-CUDA) installers.Reviewed-on: #66 Co-authored-by: Filip Leonarski <filip.leonarski@psi.ch>	2026-07-03 19:18:56 +02:00
