    55The stack that I investigated was stack 336346 (skycell.1316.089).  I chose a square that had a lot of false detections (green), and one that did not (red):
    66
    7 [[Image(falsedetbias.jpg)]]
     7[[Image(falsdetbias.jpg)]]
    88
    99I then chopped the cell that had a lot of false detections into two (top half = red, bottom half blue), and divided the pixel values by the sqrt of the variance.  A gaussian was fit to each of these parts, and it is in log space (y):
    1010
    11 [[Image()]]
     11[[Image(differentfitsfalse.jpg)]]
    1212
    13 black = the cell with few false detections,
    14 blue = the bottom half of the cell with the false detections
    15 red = the top half of the cell with the false detections
     13* black = the cell with few false detections,
     14* blue = the bottom half of the cell with the false detections
     15* red = the top half of the cell with the false detections
