  * A-007 (Heather): Make histograms of flux_sig/flux ratio.
  * A-008 (Who?): Once A-005 is done, check flux_sig/flux ratio for true positive
-
+ * A-009 (Who?): Answer Gene's questions: 1) What fraction of the detections have flux / flux_sig < 5 (the nominal cutoff) or < 3 (a possible agressive cutoff)?; 2) What is the spatial distribution of these detections? 3) 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).
