Confirmed exoplanets that are Roman-accessible in the optimistic CGI configuration, with P_access > 25% and orbiting stars brighter than V = 7 mag (solid stars). For comparison, we show the confirmed exoplanets for which we know d and can derive a as explainedin Sect. 4.1 (semi-transparent dots). The colour code indicates the corresponding discovery technique (with which the planet was identified first), as detailed in the legend. “Others” refers to all other possible discovery techniques considered in the NASA Exoplanet Archive. HD 100546 b is the only Roman-accessible exoplanet discovered in imaging, although its existence is marked as controversial in the NASA Archive.
