Contributed to the spacetelescope/jwst repository by enhancing documentation and resolving a critical bug in time-series data workflows. Expanded and clarified outlier detection documentation for the MIRI imager, focusing on supported TSO modes and configurations to streamline onboarding and reduce support needs. Later, addressed a bug in cross-slit pixel scale calculations, ensuring accurate user slit position mapping and improving downstream pathloss computations. These efforts improved data processing reliability and reduced user confusion. Work was delivered using Python and RST, with a focus on documentation, bug fixing, and data analysis, supporting more efficient and trustworthy scientific data workflows for JWST users.
