PROFILE
Koothodil Abhijith Augustintine
Worked on the cositools/cosipy repository to deliver end-to-end phase ephemeris integration and phase-resolved analysis features supporting pulsar timing workflows. Developed the PhaseEphemeris protocol with SpacecraftHistory and PhaseSelector, implemented unit tests, and created tutorial notebooks to improve onboarding and reproducibility. Enhanced data handling by refining orientation and phase assignment guidance, and addressed import and documentation issues to streamline setup. Added a targeted warning in PhaseAssigner for FITS time-coordinate inconsistencies, promoting safer data processing. Leveraged Python, astropy, and Jupyter Notebooks throughout, with a focus on scientific computing, error handling, and robust documentation to support astronomy data analysis.

May 1, 2026Month: 2026-05 — cosipy delivered a focused feature to improve correctness and user awareness around time-coordinate handling for FITS in PhaseAssigner. A warning is now emitted when PhaseAssigner.add_phase_column detects potential issues with FITS time coordinates, helping users avoid incorrect phase calculations and improving reproducibility. This aligns with our emphasis on data provenance and safer data processing pipelines. No major bugs were fixed this month; only a feature delivery. The change is lightweight, non-intrusive, and adheres to existing warning patterns in the codebase, with minimal performance impact.

Apr 1, 2026April 2026 COSIPY monthly summary: Delivered end-to-end Phase Ephemeris integration and phase-resolved analysis capabilities for cosipy, strengthening pulsar timing workflows and data fidelity. Implemented PhaseEphemeris protocol with SpacecraftHistory and PhaseSelector, added unit tests and a tutorial notebook, and refined CI/tests and documentation to improve reliability and onboarding. Finalized phase-resolved tutorials, notebooks, and data handling workflows with orientation/phase assignment guidance. Performed targeted maintenance to resolve import issues and keep docs up to date, removing accidental imports and merging conflicts. These efforts unlock reproducible phase-based livetime corrections, reduce setup friction, and demonstrate robust Python tooling, testing, and documentation practices.
