    5353 * looked up some sample regions with brighter stars in MD04 with good and not so good FWHM for Ken.

     55 * finished reworking the detectability queries to run more efficiently.
     56 * Started investigating the staticsky failures in earnest. Classified the errors. Most are failing in the "unable to select stamps for psf matching" A couple of assertion failures popped out. We also have some whose memory usage explodes 77 GB is the record so far. That one turned out to have M75 in the skycell.
     57 * That raised the question "What is happening with the other Messier objects. Found the coordinates and ran a postage stamp request to extract images from the LAP stacks. Did a quick look and for the most part aren't all bad. Further report with images will be written and placed on a wiki soon.
     58 * Decided that having a tool that would display the skycells for a given coordinate was a good idea. Spent Friday writing this program and used it to examine several NGC galaxies.
     59 * Started playing with a tool to extract extended source information from staticsky outputs and using it to annotate ds9 display. It is interesting to see where galaxies generate multiple objects and what look like false detections.
