Fig. 2
Simulated images to estimate the minimum threshold value for rlim. Simulated thumbnail images and intermediate images to compute ℛ+ are shown for a pure emission line feature considering three different instrumental PSFs with θ = 2.5, 2.0, and 1.5 pixels FWHM. The maximum pixel value is provided for each subimage. The maximum in ℛ + corresponds to the minimum value for rlim to avoid misclassification as cosmics.
