Worked on the Subaru-PFS/datamodel repository to enhance guide star data handling and improve code maintainability. Developed a new GuideStars flag attribute and implemented bitmask decoding using Python, NumPy, and FITS I/O, enabling more accurate catalog flag interpretation and supporting downstream AutoGuider workflows. Introduced the AutoGuiderStarMask IntFlag enum and a decoding utility to interpret bitmask values, improving data fidelity for guide star selection. Additionally, addressed a DeprecationWarning by updating GuideStars string dtypes to modern NumPy formats, reducing log noise and ensuring forward compatibility. The work focused on robust data modeling and targeted, low-risk improvements to existing infrastructure.

Aug 1, 2025Monthly work summary for 2025-08: Remediated a DeprecationWarning in Subaru-PFS/datamodel by modernizing GuideStars string dtypes, replacing fixed-length numpy strings 'a7'/'a1' with '|S7'/'|S1'. This minimal-risk patch eliminates noisy warnings, improves forward compatibility with NumPy dtype changes, and lays groundwork for future data-model cleanups. Commit applied: 51ab376a577773595979de1b3f4bb9d7ae8db1d4 (Remove DeprecationWarning).

Mar 1, 2025March 2025: Enhanced the data model for guide star handling in Subaru-PFS/datamodel to support catalog flag information and bitmask decoding. Delivered a new GuideStars flag attribute, updated constructors and attribute access, extended FITS I/O to preserve flag data, and added the AutoGuiderStarMask IntFlag enum with decode_gs_bitmask to interpret these flags. These changes improve data fidelity and enable more reliable AutoGuider workflows downstream.
