 As one aspect of these gradients is to determine how the dark influences the pattern, I looked at the profile for a dark detresid image (a dark frame processed using the current dark model; note that this detresid was taken ~250 days after the footprint data, and therefore is not a direct comparison) to see what residual patterns are visible.

 This detresid image shows a similar saw-tooth pattern visible along that same row of cells on the same OTA.  Checking the detproc image (a dark frame that has not had the dark model applied) shows a different profile shape:
 
-[[Image(gradient_detproc.png,400px)]]
+[[Image(gradient_darkproc.png,400px)]]
 
 This suggests that the current dark model assumes a given detector response along the cell pixel columns that possibly no longer matches the real detector response.  I am now checking a large sample of dark images to determine how this has changed over time.
