The experimental CLI and the PyROOT extra existed only for the
removed analysis packages. Version bump reflects the scope reduction
to theory-only spectrum calculation; calculation logic is unchanged.
- --normalize-to-one renamed to --separate-branches (no alias; the
name now describes the output choice: total spectrum with
intensity-normalized branches vs separate branches, each
normalized to unit area with intensities left to the data user).
SpectrumConfig.normalize_to_one -> separate_branches, CSV header
word to_one -> separate.
- every long option gains a single-letter alias: -N -i -s -m -o -p
-L -d -c -V -S -b (only -v/-q existed before)
- dry-run drops the top-level Transition: line — the per-branch
list below already reports each branch's transition type
- version bumped to 0.4.1 (pyproject, __version__, CSV semantics
docstring, TODO roadmap entry)
- Cross out B3 in TODO.md with completion details
- Export BranchConfig in __init__.py public API
- Update README to mention per-branch transition types and intensity cutoff
- Add nuclear_data.py module for paceENSDF integration and JSON input
- Add DecayInfo and BranchInfo dataclasses for parsed nuclear data
- Implement get_decay_info_from_paceENSDF() to retrieve decay parameters
- Implement load_json_input() and json_to_config() for custom JSON input
- Add create_config_from_source() unified interface for both sources
- Add bs_pnpi CLI with --nuclide, --input, --output, --plot, and detector options
- Add 23 comprehensive tests for nuclear_data module
- Add sample JSON input file
- Update __init__.py and pyproject.toml with new exports and entry point
- Add paceENSDF as optional dependency
Add CurveFitter with scipy least_squares, configurable loss functions
(soft_l1, huber, cauchy), profile likelihood, confidence intervals, and
goodness-of-fit metrics. Add CWExtractor for extracting shape factors
from beta spectra via Kurie analysis, parametrization fitting, and
g_V/g_A extraction. Includes 32 new tests (18 fitter + 14 CW extractor).
Bump version to 0.3.0.
Implemented all planned corrections:
- finite-size e/m L0 and U
- atomic screening and exchange
- radiative (electron only so far)
Added plotter and csv_export
Add implementation for the basic set of spectrum components:
Primary
-------
- Phase Space
- Fermi Function
Corrections
-----------
- Atomic:
- Screening
- Atomic exchange
- E/M and finite size:
- Finite nucleus size and charge distribution
- Radiative
