Automated Detection of Short Optical Transients of Astrophysical Origin in Real Time

Figure 4

Distribution of the distance from flash event candidate to the closest satellite from the catalogue, for events found by coincidence algorithm during night 2004.10.28/29. For comparison distances from randomly generated flashes to the nearest satellite are shown as red dots—combinatorial background is nicely reproduced. For the purpose of this analysis signal threshold was decreased to have more accidental coincidences.
