50% quartiles of the daily number of detected tracks for the 1000 Monte Carlo simulations for Scenario 4 for J-map track duration (i.e., the interval between detected tracks; see Sect. 3) of 60, 120, 240, and 480 min (blue, green, red, brown lines, respectively). The purple line corresponds to results to when no smoothing is applied to the J-maps and the same temporal width as in our original study is used. The two horizontal dashed lines correspond to four and five daily J-map tracks, consistent with the observed J-map in Paper I.
