Target Selection and Observation Modeling Tools for the Roman Coronagraph

Science reports the Space Imaging and Optical System Laboratory (SIOSlab) at Cornell University has been supporting the Nancy Grace Roman Space Telescope Coronagraph Instrument since pre-Phase A and maintains two open-source, community resources: a one-to-one port of the internal JPL Exposure Time Calculator (ETC) as a module of the EXOSIMS framework and a publicly accessible Imaging Mission Database of known planetary companions.

Under the Coronagraph Community Participation Program the team proposes activities to further develop and expand both resources, targeting modeling of astrophysical targets (A), selecting suitable observing targets (B), planning observations (D) and enabling activities (M).

They will continue development and maintenance of the EXOSIMS Roman coronagraph ETC to account for instrument model improvements and new flight instrument characterizations, and will recompute detection probabilities for all targets in the Imaging Mission Database after each update.
