leonarski_fandClaude Opus 4.8 85cf826d2e rugnux: dataset Wilson B-factor estimate + robust per-image Wilson B
Add a dataset-wide isotropic Wilson B-factor estimate, the analogue of XDS's
"WILSON LINE ... B=" which we did not export. CalcGlobalWilsonB fits ln<I> vs
1/d^2 over the merged reflections (B = -2*slope), skipping the low-resolution
non-linear region (d > 4 A) and shells past the signal limit (<I/sigma> < 1)
so the estimate is insensitive to how far the merged data were carried. It is
diagnostic only - not fed back into scaling - and is written to the mmCIF
(_reflns.B_iso_Wilson_estimate), the printed merge statistics, and the log.

Also harden the per-image Wilson B (CalcWilsonBFactor): accept the fit only
when it is well-correlated and physically plausible (0 < B < 200 A^2), else
leave b_factor unset. A bad frame (an indexing glitch, too few reflections)
otherwise produced a wildly steep Wilson line and a B of several hundred A^2
that polluted the per-image plot; NaN is preferable to garbage.

Diagnostic-only: the merged intensities and every merge statistic are
byte-identical (verified baseline vs modified on the rotation battery).

This is an UNSTABLE release. The release has significant modifications for data processing - in case of troubles go back to 1.0.0-rc.144.

jfjoch_process: Generate a dedicated file (_process.h5), which can be used as a replacement for the _master.h5 file for a reanalyzed dataset.
jfjoch_process: Improve the performance of scaling and merging, implement on the fly scaling.
jfjoch_writer: All final data analysis results are repopulated in the _master.h5 file.
jfjoch_scale: Dedicated tool for rescaling/merging existing data.
jfjoch_viewer: Fix bugs where pixel labels where displayed on a wrong pixel.

WARNING! Scaling and merging are experimental at the moment, and may not provide reasonable results for the time being.
