IQ of band-filter images recovered from mock IFS observations of the stars in the inset plot, relative to the input ε_LE for the simulation, plotted as a function of the bandwidths used for image recovery. Turbulence conditions were set to ε₀=0.83 arcsec and ${ℒ}_0$=22 m to compute ε_LE from Eq. 5. Filled and open circles correspond to mock IFS observations of the A1V-type (HD000136) and M6 V-type (HD001326) stars, respectively. The colors correspond to the central wavelength of the band filters: ε₁ = 4000Å → purple, λ₂ = 5000Å → blue, λ₃ = 6000Å → green, and λ₄ = 7000Å → red.
