This shows the results of search model analyses. The μ parameter refers to the mean of the Gaussian from which the signal-site decision variables are sampled (the standard deviation is assumed to be unity) and λ and ν parameters are the x and y coordinates of the true end-point. In addition to LLFα, which depends on the choice of α, the search model provides a second figure-of-merit
which is independent of α. NA: confidence interval cannot be calculated due to floating point overflow.
