Handbook development COS activities are a traditional-mode, new HST instrument development project coordinated with IDT led by PI Jim Green (Colorado) STScI supports COS science operations by leading development of “front- end” (operations) and “back-end” (OPUS/MAST/calibration) ground system and user support functions..
