Jun 1, 2025June 2025 for Keck-DataReductionPipelines/KPF-Pipeline: Key features delivered include master pipeline cleanup and housekeeping enhancements (robust cleanup script, pre-execution temp-file cleanup, cron-based cleanup, and processing-date temp file cleanup) and a data-quality guard that prevents 2D FITS generation unless GREEN_CCD and RED_CCD have at least two frames. Major bugs fixed include gating 2D FITS production to data sufficiency, avoiding incomplete outputs. Overall impact: increased reliability of nightly reductions, safer disk hygiene, and improved data integrity for downstream analyses, delivering business value by reducing invalid products and stabilizing automated runs. Technologies/skills demonstrated: shell scripting for cleanup, Python updates in master_arclamp_framework.py for data quality gating, cron-based automation, and disciplined version-control practices.

May 1, 2025May 2025 monthly summary for Keck-DataReductionPipelines/KPF-Pipeline: Delivered feature-rich improvements to strengthen data integrity, streamline end-to-end processing, and improve system observability. Implemented daily order-mask generation in the Masters pipeline with end-to-end data registration, enhanced configuration/scripts, and database queries to locate inputs, registering the ordermask caltype. Advanced the order rectification workflow to produce daily rectified flats required by downstream recipes, with Python tooling and configuration. Hardened file verification with MD5 checksum path improvements to ensure consistency across containers and runtimes. Upgraded infrastructure with a dedicated Masters pipeline Docker image and updated scripts. Expanded monitoring via the watchdog to cover both the pipeline-operations DB and the time-series DB with restart logic and explicit status messaging. Added robust L0 file handling, including a new Python module for L0 querying and safeguards for problematic filenames. Introduced a registration step for 2D master products prior to L1 processing to bootstrap pipelines with complete inputs, including log management and a pipeline version update.

Feb 1, 2025February 2025 progress for Keck-DataReductionPipelines/KPF-Pipeline focused on strengthening master file documentation, clarifying algorithm details, and hardening the docs pipeline against edge cases. We advanced content creation and formatting in the Master Files section, attempted math formula integration (reverted to preserve stable output due to Sphinx math limitations), and improved overall documentation quality. Additionally, robustness improvements were implemented for data parsing (FITS header), and compatibility updates were applied following restructuring of Polly. Documentation fixes (broken links and references) further improved maintainability and usability for end users and future contributors. These efforts collectively reduce ambiguity, improve reproducibility, and deliver measurable business value by enabling faster onboarding, clearer long-form documentation, and more reliable data reduction workflows.
