(A) Threshold estimates obtained on a simulated version of ASTEROID for four different example model observers. (B) Ninety-five percent limits of agreement for pairs of threshold estimates from the same four model observers. Model observers differ in their true stereo threshold, indicated by position on the horizontal axis, and in their lapse rate and the steepness of their psychometric function, as indicated by the different colored curves. Black: λ_M = 0.03, b_M = 4.885/log₁₀ arcsec; red: λ = 0.03, b_M = 14.654/log₁₀ arcsec; blue: λ_M = 0.03, b_M = 2.931/log₁₀ arcsec; green: λ_M = 0.1, b_M = 4.885. In every case the simulated ASTEROID assumed λ = 0.03, b = 4.885.
