Open Issues

  • CASA 5 and CASA 6 runs now believed to be scientifically equivalent
    • For CASA6 there appears to be a delta between running multiple tcleans in a single CASA session vs separate sessions.
  • Can we speed up the import step for the split stage.   SCG will examine where time is spent and suggest improvements and whether this should remain a s

Decisions

  • John Tobin is producing a image comparison utility
    • SCG has modified John's comparison script to allow for arguments and trivial heuristics (psf vs image etc).  Will investigate merging.
