Log stretch of a matched filter map in the NGC 5824 field. The sky pixel width is 0.2° and the map is smoothed with a Gaussian kernel of σ = 0.5°. Three panels present the same map. The white arrows in the left panel point to the stream features. The locus of the model stream is overplotted using the small red dots in middle panel. The right panel illustrates the way of creating the stream’s lateral profile (see text). The bottom right region close to the Galactic disk is masked in the middle and right panels.
