Fig. 3

Absolute minimum values of rlim as a function of θ and w. These values were determined from noise-free simulations and set a hard lower limit to avoid frequent false detections of object signal as cosmics. They are estimated from the instrument-specific value of w. The shaded area highlights the regime of significantly undersampled data, where more care is needed.
