PROFILE
Hirotaka Sekine
H. Sekine enhanced the ut-issl/s2e-core repository by refactoring the IGRF-based geomagnetic calculation routines, focusing on correctness, robustness, and maintainability. Using C++ and numerical analysis, Sekine clarified the implementation of geomagnetic field component formulas, adjusted loop bounds, and improved the order of operations to ensure accurate results, especially in edge geographic cases. The work included adding explanatory comments and hardening the code against division-by-zero errors, resulting in more reliable scientific computing simulations. Additionally, Sekine updated project documentation in Markdown, ensuring accurate publication citations and launch year details, which improved onboarding and reduced the risk of citation errors.
