Performance quality of the ML and WLS estimators relative to the nominal bound expressed in terms of the indicator and , respectively, in the undersampled regime (space-based and ground-based are on the left and right, respectively).
|FWHM||ML error [%]||WLS error [%]|
Notes. The results are presented for different values of FWHM (measured in arcsec) with F̃ = 20 004 e‒, B̃ = 25 e‒ (space-based), B̃ = 626 e‒ (ground-based), and Δx = 0.2 arcsec.
