 The plot below shows the number of detections per skycell (log scale) for the region 267 < RA < 303. The data for 10 < DEC < 20 is still processing

+== False Detections from y band stacks ==
+We have noticed that some skycells are getting large numbers of matched detections. These are caused by false detections in the y band.
+If we plot the ratio of the number of matched detections to the number of detected sources for each band we can see these outliers.
+The following plots shows the ratio for the r band versus that in the ratio in i band for each stack. The plot on the left shows the full range
+including the outliers wile the plot on the right zooms in on the values near zero.

+
+The plots for g and z show the same shape while the y band plot does not show the tail.
