- Non-photon pixels now update pedestal (push_fast equivalent)
directly in the kernel, no atomics needed
- Commented out quadrant significance test (c2): absent from
sequential CPU code, was producing GPU-only clusters.
- Added d_pd_sum to device allocations and host upload
Build (sm_89): 46 registers, 0 spills, 100% occupancy.
Verified on 256x256 Jungfrau data, 5000 frames, nSigma=5.0:
CPU 8428 vs GPU 8471 clusters, 99.8% match
0.63 ms/frame CPU vs 0.04 ms/frame GPU (~16x)
## Unified Minuit2 fitting framework with FitModel API
### Models (`Models.hpp`)
Consolidate all model structs (Gaussian, RisingScurve, FallingScurve)
into a
single header. Each model provides: `eval`, `eval_and_grad`, `is_valid`,
`estimate_par`, `compute_steps`, and `param_info` metadata. No Minuit2
dependency.
### Chi2 functors (`Chi2.hpp`)
Generic `Chi2Model1DGrad` (analytic gradient) templated on the model
struct.
Replaces the separate Chi2Gaussian, Chi2GaussianGradient,
Chi2Scurves, and Chi2ScurvesGradient headers.
### FitModel (`FitModel.hpp`)
Configuration object wrapping `MnUserParameters`, strategy, tolerance,
and
user-override tracking. User constraints (fixed parameters, start
values, limits)
always take precedence over automatic data-driven estimates.
### Fit functions (`Fit.hpp`)
- `fit_pixel<Model, FCN>(model, x, y, y_err)` -> single-pixel,
self-contained
- `fit_pixel<Model, FCN>(model, upar_local, x, y, y_err)` -> pre-cloned
upar for hot loops
- `fit_3d<Model, FCN>(model, x, y, y_err, ..., n_threads)` ->
row-parallel over pixel grid
### Python bindings
- `Pol1`, `Pol2`, `Gaussian`, `RisingScurve`, `FallingScurve` model
classes with
`FixParameter`, `SetParLimits`, `SetParameter`, and properties for
`max_calls`, `tolerance`, `compute_errors`
- Single `fit(model, x, y, y_err, n_threads)` dispatch replacing the old
`fit_gaus_minuit`, `fit_gaus_minuit_grad`, `fit_scurve_minuit_grad`,
etc.
### Benchmarks
- Updated `fit_benchmark.cpp` (Google Benchmark) to use the new FitModel
API
- Jupyter notebooks for 1D and 3D S-curve fitting (lmfit vs Minuit2
analytic)
- ~1.8x speedup over lmfit, near-linear thread scaling up to physical
core count

Matterhorn10 Transform
some other Transformations from pyctbGUI
added method get_reading_mode for easier error handling in decoders
## TODO:
- proper error handling for all other decoders
- proper documentation for all other decoders
- refactoring all other decoders to store hard coded values in a Struct
ChipSpecification
Reading multiple ROI's for aare
- read_frame, read_n etc throws for multiple ROIs
- new functions read_ROIs, read_n_ROIs
- read_roi_into (used for python bindings - to not copy)
all these functions use get_frame or get_frame_into where one passes the
roi_index
## Refactoring:
- each roi keeps track of its subfiles that one has to open e.g.
subfiles can be opened several times
- refactored class DetectorGeometry - keep track of the updated module
geometries in new class ROIGeometry.
- ModuleGeometry updates based on ROI
## ROIGeometry:
- stores number of modules overlapping with ROI and its indices
- size of ROI
Note: only tested size of the resulting frames not the actual values

- automatically run python tests
- automatically run test using data files on local runner from gitea
- fixed some of the workflows
---------

- Removed redundant arr.value(ix,iy...) on NDArray use arr(ix,iy...)
- Removed Print/Print_some/Print_all form NDArray (operator << still
works)
- Added const* version of .data()
- Comment for documentation
- Some extra tests
- New aare:to_string/string_to similar to what we have in
slsDetectorPackage
- Added members period and exptime to RawMasterFile
- Parsing exposure time and period for json and raw master file formats
- Parsing of RawMasterFile from string stream to enable test without
files
Comments:
- to_string is at the moment not a public header. Can make it later if
needed. This gives us full freedom with the API
- FileConfig should probably be deprecated need to look into it.
Meanwhile removed python bindings and string conv
This PR adds support for decoding digital data from the my320 test chip.
- Added BitOffset (strong type)
- Expand 24 to 32 bit
- Python bindings for decoding my302
- Improved docs
- added rosenblatttransform
- added 3x3 eta methods
- interpolation can be used with various eta functions
- added documentation for interpolation, eta calculation
- exposed full eta struct in python
- disable ClusterFinder for 2x2 clusters
- factory function for ClusterVector

Vadym accidentally called view() directly on an R-value frame, which
leads to a dangling view pointer.
Adjusted code such that compiler throws an error if called on an R-value
frame.

- Removed unused ClusterFile.cpp (code from before it was templated)
- Updated the list of .cpp files in CMakeLists.txt to match alphabetic
listing in the browser
- No changes or evaluation of existing tests
- Tags for including tests that require data is changed to
**[.with-data]** and **--with-data** for C++ and python respectively
- Minor update to docs
- Added missing files to the test data repo
