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

| | 23 | The 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. |

| | 30 | This 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 | |
| | 34 | I 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 |

| | 47 | This already looks a lot different than what was seen for SAS footprint. |
| | 48 | |
| | 49 | Plotting each of the cells separately and plotting the same with the x axis flipped shows that it's way more symmetric than for SAS: |

| | 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)]] |

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