Package: nestpy-test1
nestpyVisit the tutorials directory for tutorials on the nestpy calls, maintenance, and benchmark plots.These are the Python bindings for theNEST library, which provides a direct wrapping of functionality.  The library is not Pythonic at this point but just uses the existing naming conventions from the C++ library.You donothave to have NEST already installed to use this package.Installing from PyPIFor 64-bit Linux or Mac systems, instally 'nestpy' should just require running:pip install nestpyYou can then test that it works by running the example above.Installing from sourceRequirements: You must have CMake>=2.8.12 and a C++11 compatible compiler (GCC>=4.8) to build.First, you must check out this repository then simply run the installer:git clone https://github.com/NESTCollaboration/nestpy
cd nestpy
python setup.py installUsagePython bindings to the NEST library:import nestpy

# This is same as C++ NEST with naming
nc = nestpy.NESTcalc(nestpy.VDetector())

interaction = nestpy.INTERACTION_TYPE(0)  # NR

E = 10  # keV
print('For an %s keV %s' % (E, interaction))

# Get particle yields
y = nc.GetYields(interaction,
		 E)

print('The photon yield is:', y.PhotonYield)
print('With statistical fluctuations',
      nc.GetQuanta(y).photons)For more examples on possible calls, please see the tests and tutorials folders.SupportBugs: Please report bugs to theissue tracker on Githubsuch that we can keep track of them and eventually fix them.  Please explain how to reproduce the issue (including code) and which system you are running on.Help: Help can be provided also via the issue tracker by tagging your issue with 'question'Contributing:  Please fork this repository then make a pull request.  In this pull request, explain the details of your change and include tests.Technical implementationThis package is apybind11wrapper ofNESTthat usesGitHub Workflowsto build binaries using themanylinuxDocker imagefromthis page.Help from Henry Schreiner, which included a greatbinding tutorialImplementation also based onthisImplementation of GitHub test and build actions was made possible byJoran Angevaare.See AUTHORS.md for information on the developers.CitationWhen you usenestpy, please say so in your slides or publications (for publications, see Zenodo link above).  You can mention this in addition to how you cite NEST.  This is important for us being able to get funding to support this project.HistoryPatch releases mean (the Z number in X.Y.Z version) that the underlying physics has not changed.  Changes to the NEST version will always trigger a minor or major release.  If this library changes such that end users have to change their code, this may also trigger a minor or major release.1.5.2 (2022-04-11)New Physics:Perfectly vertical MIP tracks now work, and use latest beta model (Greg Rischbieter, LZ/UAlbany)Field in G4 in any direction not just vertical but e.g. radial OK, ala (n)EXO and PETALO (Paola Ferrario)Code Quality:NEST: Geant4.9.11 & C++17 compatibility achieved (Paola Ferrario, PETALO/Basque Foundation for Science)Multiple scatter code warning addressed: unused variable (Greg Rischbieter, LZ/UAlbany)nestpy Specific:N/A1.5.1 (2022-02-09)New Physics:dE/dx-based yield code moved (execNEST->NEST.cpp) for accessibility. Muons, MIPs, LIPs; random positionsInitial or average dE/dx allowed, and use of ESTAR or custom power law, with variation around a mean dE/dxloopNEST for ER restored, with 1st-principles mod TIB model of recombination parameters for sustainabilityNew multiple scatter tool allows for creation of 2+ ER-like/NR-like scatters, or mixed for inelastic, Migdal, etc.Code Quality and/or Miscellaneous Bug Fixes:random exponential smarter sampling for small ranges especially for Kr83m times (Scott Kravitz, LZ/LBNL)D-D energy spectrum user-settable, serving as example for any NR calibrations (Greg Rischbieter, LZ/UAlbany)New truncated Gauss option, w/ truncation at 0 in 1st usage to solve S2 corner case (Scott Kravitz, LZ/LBNL)nestpy Specific:N/A1.5.0 (2021-11-11)New Physics:Carried over from v2.3 beta: A new binomial random number generator (C++ default library), e- EE models, beta model with new yields and fluctuations, non-beta-ER (XELDA).New beta model is default regardless of E-field, but old one is still accessibleER model (betas and gammas weighted) is its own function, callablePb-206 ion coming off wall from alpha decay has correct Ly and Qy versus field (Thomas-Imel box model for recomb)The electron extraction efficiency model now includes “optimistic” high e- EE Aprile/PandaX fits (activatable with EPS_GAS negative)Code Quality and/or Miscellaneous Bug Fixes:C++11 -> 17 default, README updated with all new versioning requirements, but old gcc and cmake versions requested to allow backwards-compatibility with nestpy. std::clamp still doesn’t work, so similar function written by hand1.1 -> 1.08 for increasing Qy to match new Zurich W-value measurement, but with new more logical variable names both deep in code and in detector file for user, and with one factor universal in NEST.cpp; general variable renaming for greater clarityNumerous cosmetic and aesthetic changes to code, including unused variable removal, while spacing and tabbing made Google clang-format (with shell script for that now included with NEST), if/else Mac dangle warning addressedKr83m yields same but code overhauled to allow min versus max time separation flexibility and easier data comparison, with bug squashed where wrong error message got replayedNEST is now 30% faster, cf. v2.2.4, at least when using gcc 7+, despite the new binomial fluctuation function!nestpy Specific:Bindings to energy spectra generators from TestSpectra.cpp, including: tritium and C14 beta sources; AmBe, DD, Cf252 neutron sources; Spin-Independent WIMP Generators.1.4.12 (2021-11-02)Sync withNEST v2.3.0betaBeta model updated to work with LUX C-14 (medium E-fields) in addition to XENON1T Rn-220 calibration, < 100 V/cm (Greg Rischbieter, Matthew Szydagis, Vetri Velan, and Quentin Riffard of LZ)Non-beta (L-shell and M-shell) ER data now matched, from the XELDA experiment, with weighting of beta and gamma models (Sophia Farrell, Rice/XENON and Greg R. UAlbany/LZ)Work function of 11.5 eV (EXO-200, Zurich) can now be more accurately reproduced with the "remove quanta" flag set to false, matching the EXO and Baudis (new) data sets (Kirsten McMichael, RPI/nEXO and Matthew Szydagis, UAlbany/LZ)Systematic error taken into account for 3D XYZ position reconstruction with S2, per LUX Mercury paper (Claudio Silva, Coimbra/LZ).Made the default S1 calculation mode hybrid instead of full, for faster simulation of large-energy (e.g., MeV-scale) eventsTweaked the default detector example (LUX Run03) to work with the latest models and reproduce D-D and 3H bands perfectly still, while also adding units to this LUX detector header file (Szydagis)Binomial random number generator now uses default C++ library (Robert James, LZ). Code is a bit slower now (only by ~10%) but is more precise, and matches python, FlamedisxThe e- ext eff from liquid to gas is now based on both E-field (in liquid) and temperature, not field alone, combining dozen data sets spanning decades, to address concern raised by Sergey Pereverzev, LLNL. So, it's NOT just PIXeY or LLNL, etc.1.4.11 (2021-08-09)Sync withNEST v2.2.3Replaced useTiming variable by an enum and made the GetS1 result a class member.

New Physics:Liquid Xe model for NR is now better behaved at few hundred keV and few hundred in S1: no odd increase in band width caused by Nex/Ni zeroing out and kinking the recombination probability. Mean yields model unchanged, nor recombination fluctuations / skewness.
