  • Numerous meetings with Conrad and Jim regarding data integrity, speed, error handling etc
  • Now that I'm able to churn out data in bulk, speed is seen as a real issue (up to 10 minutes to create FITS detections from a 'busy' smf source) so...
  • Re-wrote FITS I/O stuff to use cfitsio directly, rather than psLib. Now more than twice as fast: remaining bottleneck is access to DVO db
  • Worked with Conrad on his 'dxlayer' including:
    • potential designs for error-handling
    • transferring some tasks to ippToPsps code so that dxlayer can remain ignorant of db schema (will save on maintenance when there are schema changes)
    • wrote fast code to convert FITS extensions to csv files using the low-level 'bulk copy' cfitsio functions (under 10secs for 70Mb FITS, which take minutes to write)
