Human-observer performances in the SPN detection-localization study. The uncertainties in A_L for the individual observers are as reported by the Swensson LROC fitting software. Uncertainties for the contrast-specific values of A_L are on the order of 0.12. The uncertainties in ${\overline{A}}_L$ represent the standard deviation in the performances of the individual observers.
