  • Correlated data archive work to be completed for all Disk-based VLBI observations correlated at Swinburne and Curtin. Copies of archive at Curtin and ATNF (Claire/Chris/Tasso)
  • Update advice to PIs on keeping the ATCA phased at 8 GHZ and above. Check CABB developments (Tasso/Richard/Chris)
  • Complete SCHED update for the LBA and update list of “standard” LBA setups. (Cormac/Tasso)
    • Merge SCHED SVN branches to new version by end of year (Cormac)
    • Coordinate SCHED changes with FS scripts. (Cormac)
    • Get Tid FS version to Cormac. (Shinji)
  • Mk5 Disks. New units to be ordered for correlation in Curtin and/or Bonn. Steven and Tasso to coordinate.
