Exoplanet Standard Definitions and Evaluation Team

In the 2015 run-up to chartering of large mission studies, it became obvious that likely studies (HabEx, LUVOIR) would consider overlapping science cases (e.g. spectroscopy of exo-Earths). The exoplanet community has had some recent experience with apple-to-oranges/apples comparisons: parallel studies, different architectures (telescope, coronagraph masks, starshades). The challenge of parallel studies is to remain consistent over time. The topic was discussed by PAGs and Senior Management: request for “common yardstick, honest broker.” The Management Plan now includes an “Exoplanet Standard Definitions and Evaluation Team.”
