leonarski_f	929e6e1fa0	FFTIndexer: pick peaks by prominence above a local background, not raw magnitude ... The per-direction peak search took argmax|spec|. The projected-spot histogram has a broad low-frequency ENVELOPE (spots cluster near the origin) whose magnitude can exceed the true lattice peaks, so on weak / pink-beam frames every direction reported a short envelope vector (~10 A) and the real 38-79 A axes never surfaced -> 0 candidate cells -> 0% indexing. (Diagnosed on the lyso jet: the FFT returned only 10-15 A vectors, the true axes entirely absent.) Subtract a running-mean background of half-width ~15 A and pick the peak by its PROMINENCE (mag - background) instead. The smooth envelope cancels to ~0 while sharp lattice peaks - fundamentals and harmonics alike - keep their height, so the real axes win. The prominence is also reported as the magnitude, so FilterFFTResults ranks directions by real-peak strength rather than envelope. Ported identically to CPU (prefix-sum window) and GPU (sliding-window in the kernel). Validation (lyso, de-novo): jet FFT 0% -> 20.5% (CPU and GPU identical; vs FFBIDX 27%); crystal 2 95.3% -> 95.5% (no regression, CC1/2 95.8 / CCref 92.7 unchanged). The ~15 A window is the validated optimum (wider over-smooths, narrower under-removes the envelope). Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>	2026-06-16 07:25:06 +02:00
leonarski_f	6133da1377	v1.0.0-rc.133 ... This is an UNSTABLE release. The release has significant modifications and bug fixes, if things go wrong, it is better to revert to 1.0.0-rc.132. * jfjoch_broker: Use httplib for HTTP server instead of Pistache * jfjoch_broker: Drop OpenSSL support * jfjoch_broker: Base work for multi-lattice support in the future * Update dependencies to more recent versions (spdlog, HDF5, Catch2, httplib) Reviewed-on: #41	2026-03-26 20:50:33 +01:00
