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_id |
| 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:
Zoomed in:
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 (and shifting by .2).
