leonarski_fandClaude Opus 4.8	40f650b9e7	scale_merge: pool the per-frame background across each rocking event in Combine3D ... Each partial subtracted its own independently-estimated per-frame background, so a weak full assembled from N frames accumulated one background-estimation variance per frame. The true background is flat over the few frames of one rocking event, so replace each partial's background by the event mean and correct its intensity by n_bkg*(bkg - pooled), where n_bkg = (sigma^2 - I)/bkg is the effective background-pixel count -- correct for weak AND strong reflections (sigma^2/bkg would over-count strong ones and over-correct them). Single-frame events are a no-op. Measured (rotation lyso @1.0 A): 1.05 A CC1/2 81.3 -> 83.0, R-meas 81.4 -> 77.2, CCref +0.2, CCxds +0.3; overall R-meas 10.0 -> 9.4%; ISa preserved (13.5).

leonarski_fandClaude Opus 4.8	ed98775ba3	rot3d: capture-aware sigma for under-captured fulls + expose per-image scale ... The rot3d combine over-extrapolates fulls reconstructed from only a fraction f of their rocking curve (min_partiality admits f as low as 0.02). Against XDS on HEWL these low-capture fulls are systematically biased HIGH (+15% at f=0.8 to +100% at f=0.3), and the bias - not random scatter - is the strong-reflection floor that hurts anomalous accuracy. --capture-uncertainty <coeff> (default 0 = off, baseline bit-identical) adds a systematic uncertainty ~coeff*(1-f)*I to each full's sigma, so the merge down-weights the over-extrapolated fulls and the error model treats their scatter as expected. Unlike outlier rejection (which trades accuracy for CC1/2), this fixes a real bias, so accuracy improves: at coeff=1.0 the anomalous peak height vs XDS rises CL_CL +16%, SD_MET/SG_CYS +5-6%, ISa 10.7->11.0. Rotation- only (no-op for stills, which never combine). Also expose the per-image scale offline: Combine3D now carries the first-pass per-image scale metadata (G, B, mosaicity, wedge, CC) forward instead of dropping it, and jfjoch_process -M writes <prefix>_image.dat from it (the offline self-scaling result was otherwise unobservable - process.h5's per-image arrays are only filled on the online path). This enabled the XDS DECAY comparison (jfjoch G tracks XDS, r=0.93). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-27 19:41:20 +02:00
leonarski_f	54c667190f	v1.0.0-rc.155 (#65) ... 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: Remove pixelrefine option (replaced with ProfileIntegrate2D) * jfjoch_viewer: Some graphical improvements. * jfjoch_viewer: Simplify und unify data analysis settings. * jfjoch_writer: Add TCP keepalive to increase robustness if jfjoch_broker "dies" in the middle of data acquisition.
