Contrast limit as a function of angular separation, with simulation parameters detailed in Table 2. The upper panel illustrates the contrast dependence on waveband for a 100m baseline. The lower panel displays the contrast limits for a 200 m baseline. The shaded area represents a range of K band Strehl ratios, from 88% (worse contrast limit) to 98% (best contrast limit). At short wavelength, the contrast range is limited by the Strehl. In the K and L bands, the contrast range is predominantly limited by thermal background noise. The inner working angles are constrained by both the telescope’s point spread function and the interferometric resolution, both linear function of wavelength.
