Thanks, Mr. Wicklin, for the prompt response. Although the process (meteor events) is Poisson, the spatial pattern of detection of meteors by our camera network may not be CSR due to limitations of range, sensitivity and sub-optimal aiming. A region within the entirety of the area of detections that can be shown to "approach CSR" is thought to be adequately monitored. The goal is to expand that area by adding additional cameras or optimizing the aimpoints of existing cameras in the network. I've read your post on computing highest density regions in SAS and that's certainly relevant to this problem. But I am looking not only for the region of highest density but whether that known region also can pass a test for "CSR-hood". Thanks again for taking time to consider my question.
