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): ||filter ||chip || || 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: [[Image()]] Zoomed in: [[Image()]] 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. [[Image()]] [[Image()]]
