 +**Actions arising**
 +
 +CARRIED FORWARD/​UPDATED/​CONTINUING
 +
 +  *  LBA data archive consolidation and copy at CASS. (CASS, Curtin)
 +    *  LBA data archive. Need ATNF disk space (Chris,​Tasso,​ Shaun) ** Continuing **
 +
 +  *  ATCA phasing. Check performance and implementation (Jamie S, Richard)** Updated **
 +    *  Definitely need >200 mJy calibrators. Stress in documentation. (ATNF)
 +    *  Ask PIs to nominate phase-cals and check fluxes BEFORE scheduled observations (Phil, Jasmie S)
 +    *  Extract phase-cals from Vex files and check at ATCA before run (Chris, Jamie S.)
 +    *  Need at least 6 cycles for auto-phase = 30secs if 5sec integration.
 +      *  Phase-impact on phase-ref and calibration?​ Phase jumps?
 +      *  consult with Ojha re auto-phasecal for TANAMI (ATNF)
 +
 +  *  ATCA Tsys via CABB (CASS) ** Updated **
 +    *  Consult with Carrad and Sault about Tsys implementation on the CABB (Tasso) ​
 +
 +  *  Observer training and remote observing (Tasso) ** Continuing **
 +
 +  *  Wiki logs (All) ** Continuing **
 +    *  Log transfers quickly to FTP area and/or Wiki (ALL) ** Continuing **
 +    *  Annual "​best"​ wiki-log competition. To be judged by correlator at annual Ops meetings. (Cormac)
 +
 +  *  Pawsey centre access for VLBI and eVLBI (Chris, Cormac) ** Continuing **
 +
 +  *  Linear to Circular polarisation conversion. (Chris, Richard, Cormac) ** Continuing **
 +
 +  *  Monitoring "​check-list"​ for ATNF telescopes (Chris, Jamie S) ** Continuing **
 +
 +  *  For ATCA include in Wiki log: ref ant, pad, tied-array. Default ant03 on W104. (Jamie S, ALL observers)
 +
 +  *  Curtin Xcube testing. Unit installe at ASKAP. Commission. (Chris, Cormac, Tasso) ** Continuing **
 +
 +  *  On-source info from ATCA. Fix cgi scripts (Chris) ** Continuing **
 +
 +  *  DA role during LBA sessions (Phil, Tasso, Jamie S)
 +
 +  *  Procedures for raising Ho observers on Skype. Telephone? (UTas)
 +    *  Implement lists on Skype and/or Wiki for observers(ATNF)
 +
 +  *  Get Ww FS log comments onto Wiki. Use UTas "​floggit"​ script and automate? (Stuart, Chris, Jamie M.)
 +
 +  *  Fix recmon to track correct experiment name, especially due complex recordings for Ellingsen (Chris, Jamie S)
 +
 +  *  List Mk5 rtfc times for each observation from schedules (Cormac, Chris)
 +
 +  *  RadioAstron schedules and check setups (Chris)
 +
 +  *  Use new numbers for ATCA (4077 for DA; 4078 for Observer)
 +
 +  *  For wideband systems more efficient to stop data recording in slews/stops AND better effieciency in correlator.
 +    *  Adopt Mk5 systems?
 +
 +  *  Cd upgrades
 +    *  DAS replacement by dBBc (UTas). ​
 +    *  L-band sensitivity measurements. (UTas)
 +
 +  *  Tid tests for JPL DAS and Mk5c recorder ​
 +    *  Let JPL know re VDIF format (Chris)
 +    *  Web monitoring? Ports?
 +
 +  *  ASKAP VLBI monitoring (Chris, Jamie S)
 +
 +  *  Xcube testing (Chris)
 +
 +  *  CABB wide-band proges?
 +    *  Email Tim Bateman and get report (Tasso)
 +
 +NEW ACTION ITEMS
 +
 +  *  Cd drive-PC. Fix in short-term. Replace long-term? (UTas)
 +
 +  *  Ho, Cd need setup information early. Problems when schedules are late. (Phil, UTas)
 +
 +  *  Ensure correct wraps and limits are supported in Vex, especially for At and Mp. (ATNF, Cormac)
 +
 +  *  Setup of circ pol hybrids at Mp. Need to tweak (ATNF)
 +
 +  *  Tsys logs from Mp may be wrong if polarisation hybrid not setup properly. Need to average the 2 channels (ATNF)
 +
 +  *  Mp L-band and X-band low power and no atten to adjust. Check with Jock (ATNF)
 +
 +  *  Pks update of documentation. Polarisations are usually swapped. (ATNF, JER)
 +
 +  *  Pkvsi1 and pam-store disks dead! Check re backups (ATNF)
 +
 +  *  Antenna positions at ASKAP. May need geodetic run for new antenna. (ATNF, JER)
 +
 +  *  Train/​qualify more PIs for ATNF remote observing (ATNF)
 +
 +  *  Investigate more remobs for UTas telescopes (UTas, ATNF)
 +
 +  *  Streamline monitoring. Check ssh tunnel setups. (Jamie + Jamie, Chris)
 +
 +  *  Disks to Cd )Hayley)
 +
 +  *  grid-ftp on Cortex. Move to new systems (Cormac)
 +
 +  *  Supercomputer for DiFX. Approved. Initiate port. (Cormac)
 +
 +  *  Coordinate data transfers so full experiments are ready for correlation (All, Hayley)
 +
 +  *  Liaise with Ojha re auto-pcal in his observations (ATNF)
 +
 +
 +
 +STANDING ACTION ITEMS
 +
 +  *  Plan for replacements of old LBA DAS and some failing recorders.
