+Are there false detections on skyprobe?
+
+Short answer: No. There are not enough detections. 
+
+I put the chip stage images on /data/ipp010.0/heather.  The camera stage was not set up to save the fits files, and I just grabbed already processed data. We do not go past camera stage for skyprobe.
+
+These are the images (all MD01):

+||   g    ||  191434    ||
+||   r    ||  191435    || 
+||   i    ||  191438    ||
+||   z    ||  191491    || 
+||   y    ||  191440    ||
+
+For skyprobe, I just looked at g, because g was the ugliest of gpc1 (with the most false detections).  
+
+Here is what skyprobe's detections look like:

+
+There are many things not detected in skyprobe.  We need to tweak psphot to find them.

+
+
+
+I generated histograms, similar to those in http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/ZoologyInvestigations2.  This was done in g band only.  The first is a histogram of pixel/sqrt(variance), the y axis is in log scale.  The second histogram is the same, but the red dots are from flipping the histogram.
