     8XY27 is the same chip that I used before for investigating false detections, here it is for this image:

     23The distribution of the false detections appears a bit different for this MD field - previously, there would be entire cells that were just bad. This doesn't seem to happen like it did for the SAS footprint.

     30This is a zoom of XY27 in ds9.  The numbers correspond to the cells that I investigate down below.  Some of these cells had a lot of streakies/and/or/false detections for SAS footprint.

     33
     34I plotted a histogram of pixel/sqrt(variance) for each of the cells.  The colors are as follows:
     35
     36 * 1 = red
     37 * 2 = orange
     38 * 3 = gold
     39 * 4 = yellow
     40 * 5 = green
     41 * 6 = darkgreen
     42 * 7 = blue
     43 * 8 = violet

     47This already looks a lot different than what was seen for SAS footprint.

     49Plotting each of the cells separately and plotting the same with the x axis flipped shows that it's way more symmetric than for SAS:
     50
     51 * 1 [[Image(1.png, 200px)]]
     52 * 2 [[Image(2.png, 200px)]]
     53 * 3 [[Image(3.png, 200px)]]
     54 * 4 [[Image(4.png, 200px)]]
     55 * 5 [[Image(5.png, 200px)]]
     56 * 6 [[Image(6.png, 200px)]]
     57 * 7 [[Image(7.png, 200px)]]
     58 * 8 [[Image(8.png, 200px)]]

     60All of these plots are for the single chip stage. I am working on doing similar investigations for the stack stage.
