leonarski_fandClaude Opus 4.8	eccd10a0a7	integration: neighbour-mask the profile-fit background ring, widen r3 8->10 ... ProfileIntegrate2D::BoxSum now excludes every predicted reflection's r2 disk from the r2..r3 background annulus (mirroring BraggIntegrate2D), so a neighbour Bragg peak can no longer bias a reflection's background high and over-subtract. With neighbours excluded the annulus can safely widen, so the default r_3 goes 8 -> 10 (more background pixels, lower-variance estimate). Measured (rotation lyso @1.0 A, external CCref/CCxds vs XDS): 1.05 A CCref +1.3 / CCxds +1.3, R-meas -5 pts, low-res R-meas unchanged. Serial (Jet8 @0.0002 bandwidth): 1.68 A CC1/2 +3.9 / CCref +1.1, 1.58 A +4.0 / +1.6. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-29 22:41:14 +02:00
leonarski_fandClaude Opus 4.8	bbd888dcc3	integration: gate the background-ring sigma-clip to stills (bandwidth>0) ... The 76e88b0f sigma-clip (reject ring pixels above mean+3*sqrt(mean)) de-biases bandwidth-streaked high-resolution stills, but it ran on all data. On rotation (no streaks) it clips legitimate high background pixels and biases the mean low, slightly inflating weak intensities and hurting the anomalous signal. Gate it to bandwidth>0 (stills), matching how the 814dff34 radial-profile change is already gated. Rotation lysozyme (self-scaled, smooth-g, -A): anomalous S-peak 0.84x -> 0.86x of XDS (SD_MET 11.71 -> 11.94, CL_CL 1.28x -> 1.25x), ISa unchanged. Stills (bandwidth set) are byte-identical (clip still applies). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-29 19:02:47 +02:00
leonarski_fandClaude Opus 4.8	814dff34cb	integration: radially-elongated profile for bandwidth-streaked high-res stills ... 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>	2026-06-28 12:01:56 +02:00
leonarski_fandClaude Opus 4.8	76e88b0fca	integration: sigma-clip the background ring to de-bias high-resolution stills ... Weak high-resolution still reflections were systematically over-subtracted: a bandwidth-streaked high-res spot (or a neighbour) leaks into the r2-r3 background annulus and biases its mean high, so the subtracted background is too large and the merged high-resolution intensities go negative (seen as reproducibly negative <I/sig> at 100% completeness and high multiplicity past ~1.9 A). Add one high-outlier sigma-clip pass to the box-sum background (reject ring pixels above mean + 3*sqrt(mean), recompute) so the contamination no longer inflates it. A clean Poisson background is essentially unchanged (~0.1% exceed the cut). On the HEWL serial-stills jet this de-biases the high-res band - <I/sig> 2.03 A 0.9 -> 1.6, 1.79 A -0.1 -> +0.7 - extends the usable resolution ~2.2 -> ~2.0 A and improves overall R-meas 130 -> 124%, with CC1/2 and CC-vs-reference neutral. The rotation crystal is unchanged (ISa 19.1), its clean backgrounds being barely clipped. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-28 11:50:31 +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.
