Notes. The sensitivity limits are defined for the following precision criteria: σV = 0.1, σψ = 5°, and σφ = 4°, to be achieved per spectral channel after one minute of observation. Any source brighter than these limits will provide a better precision. The symbol ’−’ means that the combination resolution-versus-band does not exist. The N band bias error contribution is dominant in the differential phase. Magnitude 0 in L (at 3.5 μm), M (at 4.75 μm), and N (at 8.5 μm) bands corresponds to 290 Jy, 165 Jy, and 50 Jy, respectively.
