    42  * A-009 (See details): Answer Gene's questions:
    43    * 2) (Serge/Roy/Heather) What is the spatial distribution of these detections?
    44    * 3) (Who?) What does the histogram of pixel value / sqrt(pixel variance) look like in areas / cells with large numbers of these detections?  Should be a Gaussian with a width of 1, but if there is excess noise from the camera in some areas, the width will be > 1 (we underestimate the variance).
