Jun 1, 2025June 2025 — gafusion/omas: Delivered focused enhancements and stability fixes for DIII-D data workflows. Implemented Charge Exchange Diagnostics Enhancement to add Ion Temperature and Zeff TDI entries with proper time alignment for improved plasma diagnostics accuracy. Fixed boundary inclusion in core_profiles_strict_grid by updating the rho_tor_norm check to <= 1.0, ensuring boundary points are included and data selections remain correct. These changes raise data quality, reliability, and downstream modeling fidelity, aligning with business goals of accurate diagnostics, reproducibility, and developer-focused maintainability.
