Over nine months, Kyle Bechtol developed and optimized survey scheduling and data analysis workflows for the lsst-ts/ts_config_ocs and lsst-sitcom/sitcomtn-149 repositories. He engineered Python-based configuration enhancements for the MTScheduler, introducing features like hexgrid dithering, band sequence optimization, and reproducible observation setups to improve survey efficiency and data quality. Leveraging Jupyter Notebooks and SQL, he delivered robust data visualization and analysis tools, integrating repository data access for reproducible research. His work emphasized maintainable, version-controlled configuration management and technical documentation, enabling more reliable, automated survey operations and supporting project governance with clear, publish-ready reports and executive summaries.
August 2025: Delivered a feature in lsst-ts/ts_config_ocs to optimize MTScheduler for SV minimal field surveys by updating the band sequence from ['r','i','z'] to ['i','z','y']. Implementation via commit 3ec706e7c32ed64964829891b8acfae741bfc7a9. No major bugs fixed this month; minor maintenance and refactors were limited. Impact: improved telescope time efficiency and survey cadence; enabled better data quality in minimal-field surveys. Skills demonstrated: Python-based scheduler configuration, Git/version control, change management, cross-team coordination with ops and planning teams.

In 2025-01, delivered documentation-focused updates for ComCam Observations, DCR Documentation, and SITCOMTN-149 technical reports. The work included adding a new DCR subsection, incorporating maglim PSF figures, expanding on-sky observation content, refining figure descriptions, updating the SITCOMTN-149 abstract/introduction, and correcting typographical issues across related documents. Revisions addressed PST comments, ensured only complete sections are displayed, and highlighted versioning notes and the preliminary nature of results. The result is improved readability, consistency, and publish-readiness across SITCOMTN-149 materials.
