Month: 2026-04 — Focused on delivering a major enhancement to the PyGRB workflow in gwastro/pycbc, integrating Dynamic PSD generation and Injection SNR optimization to improve realism and reliability of injection campaigns and sensitivity estimates. Key elements delivered this month include time-varying PSD generation, optimal SNR computation for injections, and data handling for net_opt_snr, with integration into plot results and an SNR columns option on the injection node. These changes directly improve end-to-end PyGRB throughput and the accuracy of performance metrics used for decision-making. Robustness and maintainability improvements were implemented alongside feature delivery, including refactoring of the optimal SNR calculation logic, enhanced error handling for missing calculate_psd sections, and code cleanup. PSD directory naming was standardized to 'psds' with removal of legacy tags, improving consistency across the repository.
