 The new dark has finished, and although there does seem to be a weak trend in the residual slopes with dateobs, these slopes have been greatly decreased relative to the previous dark iteration:

+=== New dark footprint results ===
 
+I've reprocessed the g-filter footprint data with the new dark (including the continuity correction), and it is currently stacking (label czw.footprint.dark,data_group = czw.20120308.footprint.g).  The individual frames appear to have a smoother background, and this is reflected in an improved number of orphan detections.  Directly comparing to the previous footprint reductions as before:

+[[Image(relative_detections.png,400px)]]
+
+shows that the new dark model significantly decreases the number of singly detected objects.
