Spectrum for ε Indi Ab, generated from ATMO2020 assuming a 3.25 M_Jup, 3 Gyr planet, and equilibrium chemistry; the chosen M' and N2 bands are marked. Also shown is the extreme scenario of a 350 K, Earth-sized blackbody moon, for which it is clear that the planet still dominates by ~2 orders of magnitude in M', while the moon contributes an appreciable fraction of the flux in N2, such that a spectroastrometric signal may be observed between the two filters. We note that the region from 5.5 to 7.5 µm, though it has promising absorption regions, is inaccessible from the ground.
