News / Meetings / Visitors

  • Welcome Neil Schweighart
  • Bug in Cycle 5 non-square mosiacs - some re-processing required, investigation ongoing

    • Only affects new lustre at CV
    • No easy SW fix


  • 5.4 development (should be) complete - branch imminent (not a release branch)
    • Pipeline and JAO integration bug fixes will go in to branch
    • Final ALMA release 5.4.0 will occur after JAO completes testing (~ September)
    • VLA/VLASS release 5.4.1 TBD when they are ready - several additional requirements/development going in to this one
  • 5.5 development cycle starting now
    • Will set up new Confluence page
    • Send development item ideas to Ryan
    • Stakeholder meetings and science requirements will be delayed another ~3 weeks
    • Will use interim time for CASA 6 work and design inspections


  • Need to decide whent to branch.
  • The final VLASS blocker (RFI flagging heuristics) is in. Updated after the meeting. B Kent reported an issue in weblog. So it is not quite ready yet, but I believe it is close.
  • ALMA still has some tweaks
  • most of the tclean and performance issues are in managable level (?)
