This library provides numerical accuracy matching the original Fortran code by N. A. Tsyganenko to within 12 decimal digits (8E-12D). For external magnetic field models, accuracy is raised to 13 digits (1E-13D).

Validation

The implementation is rigorously validated against the original Fortran code using our comprehensive testing framework. See Unit Testing Framework for details on test data generation and verification procedures.

Benchmarks

Comprehensive performance benchmarks are available to measure the library's efficiency. For detailed benchmark results, methodology, and running instructions, see the benchmarks documentation.

Tech stack

Native AOT compilation

To build the project with native AOT compilation, execute the following command (depending on the target platform):

dotnet publish --framework net9.0 -c Release -r linux-x64

dotnet publish --framework net9.0 -c Release -r win-x64

dotnet publish --framework net9.0 -c Release -r osx-x64

Licensing

This C# implementation is a derivative work of the original FORTRAN code by Nikolai Tsyganenko, and is distributed under the same GNU GPL v3 license.
