Worked on the cta-lstchain repository to enhance the calibration workflow by introducing flexible calibration file creation. Developed a Python command-line interface that allows users to specify Cat A calibration and systematics files as arguments, enabling configurable and reproducible calibration pipelines. This approach reduced manual setup steps and minimized the potential for human error during calibration. The work focused on parameterizing input file selection, leveraging skills in data processing and file handling to streamline the process. No major bugs were addressed during this period, with efforts concentrated on delivering this feature to improve workflow efficiency and reproducibility for calibration tasks.
