October 2025 monthly summary for lsst-ts/ts_observatory_control focused on reliability improvements for Hexapod command execution and clear release documentation to support downstream automation and user-facing accuracy. Delivered feature enhancements with a corresponding release that improves stability and configuration consistency.

Month: 2025-05. Summary: Focused on stabilizing diagnostics for hexapod and rotator subsystems within lsst-ts/ts_xml. Expanded error handling by introducing new error codes and aligning enums across modules, enabling faster fault isolation and improved reliability. This work directly supports reduced downtime, better operator visibility, and easier maintenance in production environments.

April 2025 monthly summary focusing on key features and business value. Implemented core hexapod enhancements across two repositories to improve stability, precision, and automation readiness. Key features delivered include Hexapod Configuration Upgrades in ts_config_mttcs (MTHexapod v5, applied_force_offset, and new step_size_* controls) with GUI and laser tracker defaults, and Hexapod Control: Discrete-step Movement and Offset Commands in ts_xml (moveInSteps, offsetInSteps) with accompanying documentation. Impact includes safer closed-loop operation, easier tuning, and more reliable automation for hexapod-based tasks. Technologies demonstrated include hardware-in-the-loop configuration management, versioned configuration sets, custom command interfaces, documentation practices, and cross-repo integration for traceability.

March 2025 - lsst-ts/ts_xml: Key feature delivery focused on improving rotator error handling and documentation to boost reliability and operator clarity.

February 2025 performance summary covering four LSST TS repositories. Delivered features and fixes focused on hardware verification, monitoring, and configuration correctness, with clear business value in reliability, alerting, and consistency. Highlights include the addition of a verification stage for the hexapod warmup script, a new overcurrent watcher rule for MT hexapods, a rotator GUI port fix, and torque unit documentation updates.

January 2025 performance summary: Delivered configurable MTHexapod runtime parameters and GUI/port alignment, cleaned up configuration naming and deprecated unused parameters, and delivered a major overhaul of the Warmup Hexapod workflow in externalscripts. These changes deliver safer operations, improved reliability, and clearer maintainability with reduced downtime and smoother deployments.

December 2024 focused on improving MT hardware reliability and diagnostics, with no explicit major bug fixes recorded. The work delivered enhances fault isolation, accelerates deployment readiness, and strengthens the camera control stack’s operational resilience across ts_xml and ts_config_mttcs.

November 2024 monthly summary for lsst-ts work on ts_config_mttcs and ts_config_ocs. Key features delivered: 1) MTHexapod v3 Camera Temperature LUT Configuration: Added enable_lut_temperature boolean (default false) and updated camera_config and m2_config in _init.yaml. Commit: 9e7d567c57b2398d7cf182a1ceb4e25132872eba. 2) Watcher System Configuration Tuning for Error Detection and Performance Monitoring: Refined watcher config with higher force error thresholds in summit.yaml (axial/tangent values, max counts) and adjusted MTMountAcceleration. Commits: dd0293a596403dd8aa24cbdfc9168040a4348712; b90d29042961bae437282667b7ffe53137980f4c. Major bugs fixed: No major fixes reported in these repos this month. Overall impact and accomplishments: Improvements enable explicit control of temperature LUT for hexapods, improved error detection and performance decay measurement, leading to better instrument uptime and data quality, and more reliable operations. Technologies/skills demonstrated: YAML-based configuration governance, cross-repo coordination, version control discipline, and configuration validation planning.
