Accepted observing programs are assigned a Program Coordinator (PC), whose role is to help the observer deliver a Phase II program that is syntactically correct and will schedule successfully on the telescope.Certain types of programs (Large, Treasury, DD, ToO, moving-target, or those using complicated observing strategies or require bright-object checking) will also be assigned a Contact Scientist (CS). The role of the CS is to provide advice on observing strategies, and to answer specific questions about instrument performance. Observers who are not automatically assigned a CS may request one. The CS is generally an Instrument Scientist involved in the calibration and characterization of the primary instrument used in the observer’s program. The role of the CS ceases at program execution. Please contact the STScI Help Desk (firstname.lastname@example.org) for post-execution assistance.
