• IPP/PSPS interface
  • Memory problem - psFits/Lib functions using huge amount of memory. Now writing tables per CDD (as in spec) instead of one big detections table.
  • Got Maui cluster access, learned how to locate diffs/stacks etc.
  • Made changes to FITS file structure based on meeting with Conrad.
  • Speed issues - psFits/Lib very slow. Four minutes to write 75Mb file. Optimised some code, but more needed.
  • Now writing out FITS for diff stage (many fields missing, to be decided upon).

• Rolloff analysis: ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/EdgeRolloff Generated statistics to look at which chip/cell combinations have worse rolloff issues. Still need to finish this analysis.
• Nightly stacks: Wrote code to automatically create nightly stacks. It identifies the completion of summit_copy, applies burntool to the data if needed, queues the chip->warp processing, and queues the stack processing when the warps are complete. More testing would be useful. Current processing listed at: ​http://svn.pan-starrs.ifa.hawaii.edu/trac/ipp/wiki/NightlyStacks
• Moved nightly stack data off of ipp026 in case hardware problems cause it to lose data this weekend.
