• Selected exposures for and built a reference stack for the new STS fields. 250 exposures with fwhm_major < 1 arc second where chosen.
• changed stacktool -definebyquery to accept multiple -skycell options so that stacks for a subset of a collection of skycells may be easily queued.
• spent some time investigating why some sts stacks failed. The skycells were all in the very corners of the observations and the inputs did not have enough pixels for ppStack to process. (We require >= 10% good pixels. These input warps had less than 3%).
• Performed a magic test using difference runs using the new stack as a template. The results were abysmal. Many more false streaks were detected and the masking was much higher than when warp-warp diffs were used. We are going to need to adapt the IPP to handle 3 exposures per night.
• Finished coding and testing the new relastro -high-speed and the associated code reorganisation. This task took much longer than we expected. Wrote a note describing how to use the new code and sent it to a couple of users for testing.
• 1 1/2 days as processing czar. Due to lack of space on the wave3 nodes the wave1 nodes are getting lots of nfs activity and they often overload. Several jobs left corrupted files which needed to be fixed by hand.
• Gathered up raw and processed images from the standard star observations for John Tonry to analyze.
• debugged an ppStack failure. We decided it should be investigated futher so we saved the data from clean up and filed a ticket on the problem.
• installed a new ipp at MPIA in Heidelberg.
