Coronagraphic observations ‐2 • monte carlo analysis over broad range of masses, ages, shows nircam (f210m, f250m, f300m, f335m, f430m) + miri (f1065c, f1140c, f1550c) yields masses, radii, entropy, etc to 10% for known planets.
Such projects face many well-documented optomechanical challenges, but of equal importance is the data analysis. While coronagraphic theory and simulations are developing, significant effort is required to attain a greater empirical understanding of the highly complex coronagraphic images these experiments will produce.
