leonarski_fandClaude Opus 5	5830f78d57	Revert the azimuthal-integration sigma clip ... Removes azim_int_settings.sigma_clip / rugnux --azim-sigma-clip and the clipping machinery in AzIntEngine. This is a partial revert of a6be35ccd - the ice-ring-mask removal that commit also carried stays. Sigma clipping remains where it started and where it is needed: inside the adaptive spot finder, at a fixed 3 sigma on raw counts, feeding the detection threshold and the ice score. The option made the workflow harder to reason about than the quantity was worth. It gave azimuthal integration two meanings behind one setting - the bin mean and the background under the peaks - which the azimuthal-integration workflows do not need. It also did not compose with the fused GPU engine, which supplies the profile from its PLAIN pass: on the default rugnux, viewer and receiver path the setting was silently doing nothing (measured, the profile came out identical to the unclipped run to 1e-6 with identical per-bin pixel counts). Making it correct is not a matter of gating that one shortcut - it means separating the workflows (azimuthal integration, MX rotation, MX stills, geometry calibration) and deciding per workflow what the profile is for, which is a larger change than the option earns. The default path is unaffected: over 20 images of a rotation dataset the radial profile, the per-bin pixel counts and the spot counts are unchanged.

leonarski_fandClaude Opus 5	a6be35ccdb	Azimuthal integration: optional sigma clipping of the reported profile ... The profile is the MEAN of each bin, so a few strong reflections landing in a bin lift it exactly as a smooth powder ring does. That is the wrong quantity whenever the profile is wanted as a background rather than as a measurement of what is in the bin - the ice score being the case in point, where reading a plain profile INVERTED the metric: over 37 rotation crystals the two highest-scoring crystals had no ice at all. The adaptive spot finder already computes the right thing, a sigma-clipped per-resolution-ring background, as a byproduct of its own threshold. Where it runs, the ice score uses that. Where it does not - --no-adaptive-spots, --azint-only, and anything reading the profile the broker wrote - there was no way to get it. This adds one: azim_int_settings.sigma_clip (rugnux --azim-sigma-clip), 0 = off, minimum 2 because a tighter clip rejects a large part of a clean Gaussian bin and biases the estimate low rather than removing outliers. Two clip passes follow the plain one, matching the finder's recipe - the first pass's standard deviation is itself inflated by the peaks being removed, so one pass leaves a threshold that is still too generous. A bin with fewer than eight pixels is left alone: at the detector edge and behind the beam stop there is no spread to clip on. Both engines do it. On the GPU the accept range is computed by a small kernel and stays resident, so a clip pass is one more read of the same pixels and no round trip; the two accumulation kernels take the range as a pointer that is null on the plain pass. Measured on a JUNGFRAU rotation dataset, non-adaptive path: azimuthal integration 0.02 -> 0.06 ms per image, exactly the 3x the extra passes predict, against a 0.34 ms per-image total. Note what the result IS: the smooth background under the peaks, not the bin mean. It should not be switched on where a ring's integrated intensity is wanted - the powder-ring geometry fit reads ring peaks, and those are what a clip is designed to remove. Off by default, so nothing changes unless it is asked for. Not exposed over the REST API - that needs the generated model regenerated, which is a separate step.
