Basic summary of the current situation (Nestor):
- We know there is demand from the community for higher efficiency operational modes for times series. The motivation is well documented in Batalha et al 2018, who quantify the improvement in spectral precision with 100% efficiency read modes as a function of magnitude across the IR wavelengths covered by JWST.
- But questions remain:
- What would be the gain for different types of transiting exoplanet observations, e.g. transit vs eclipse vs phase curves?
- What is the overall science gain for JWST?
- Do the changes needed for the high-efficiency operations risk introducing new or increased systematic noise sources
