This week was a clean up odds and ends week for Bill.

• Added option to dsgetfileset to decompress files when downloaded. Requested by a postage stamp user.
• Update get_image postage stamp jobs to work with the restructured system. Users may now request bundles of destreaked data through the postage stamp interface.
• Discovered a problem due to changes in the way diff outputs are structured that caused updates to fail. Fixed by retrieving the original location from the database and using that during updates. This required changing the tasks and scripts at each stage of the pipeline so spent a bit of time testing this thouroughly using simtest.
• Tracked down problem caused simtest to generate too many stars. Checked in a workaround and filed a ticket for the root cause. (config file problem).
• investigated problem where dvoImagesAtCoords reports that a given RA and DEC is contained in multiple chips on an exposure. The root cause is due to using a transformation outside of it's valid range. Consulted with Gene and he suggested a fix that will take some time to implement. Since the problem is rare, filed a ticket and defered the problem for now.
• Spent several hours with Heather and Gavin investigating a strange problem where processes on the cluster lose track of their current directory. It may be due to the home directory relocation confusing nfs.
• Fixed a couple of bugs triggered by users postage stamp requests.
• Fixed some problems with Destreak cleanup and update with regard to the camera stage masks.
