The Roman Coronagraph Community Participation Program: data reduction pipeline astrometric calibration

The Roman coronagraph community participation program has led the development of a python-based, open source data reduction pipeline (corgidrp) to quantify the performance of the Roman Space Telescope coronagraph instrument and to process its data products. Here, we present the astrometric calibration function within the greater data reduction pipeline, outline the methods for computing critical astrometric calibration measurements, and contextualize this calibration process within corgidrp. Additionally, we discuss the results of end-to-end testing and show that all formal requirements for this calibration step are satisfied.
