  1. Science highlights:


Events/Outreach:

 

Dillon Transient Update

    • Dillon has been working on transient pipeline, polarized sources
      • ~1300 “real-time” transient sources detected
      • ~65K square degree imaged in Stokes V
      • Request for people to find a place for calibrated MS file storage permanently.


CANDIAPL/CIRADA Update

    • CANDIAPL was funded and has signed its Inter-Agency Agreements with all universities. Money should start flowing soon.
    • CIRADA quicklook is being maintained currently and GRS is looking to transfer it to CADC for long-term support.
      • GRS has funding support through ~Nov 15 for the developer to do this.



  • Talk: “VLASS Polarimetry Analysis Update” - Lerato Sebokolodi
    • GRS Comment for now:
      • The VLASS sub-tile table list for a given connected source-region could be created on the fly using astroquery.CADC using a small radius centred on a source.
    • GRS Minor question for now:
      • Regarding division by I, will there be some storage of the I used for 3-D/2-D. I imagine this would require including a Stokes I image as an HDU,
    • GRS: Minor question for off-line:
      • Have you considered smoothing the image before computing a connected source region? With the “right” smoothing radius, you might be able to reduce the number of non-connected regions that way.



Discussion
Future of CIRADANotes

    • Comments from the SSG


VLASS Epoch 4

  • Questions:
    • Is the scientific case for a 4th epoch strong enough to justify the VLA time/staff resources?
    • Is the data processing plan realistic?
    • Will VLASS remain competitive with other surveys/future instruments?
    • Could VLASS observing and data processing for Epoch 4 be optimized?
  • Timeline:
    • Sept 3: Draft outlines Epoch 4 review talks due to SSG
    • Sept 10: Epoch 4 review talks due to Tony Beasley
    • Sept 17: VLASS Epoch 4 review
    • Charge to the committee



Future meetings: (subject to change; check your email/Slack for updates)

    • September 9 at 1pm EDT / 11am MDT / 17:00 UTC
    • October 7 at 1pm EDT / 11am MDT / 17:00 UTC
