   VLASS News:

  1. Data processing: Mark and Amy
    • Nearly done with VLASS2.1 SECI using the mosaic gridder (~51%)
    • Starting recalibration of VLASS2.2 where needed in preparation for 2.2 mosaic gridder SECI.
    • Progress on testing 1” pixels?
      • Frequency-dependent taper?
      • 3” beam with 1” pixel testing in progress
      • Direct comparison between previous polarization validation cube
    • Polarimetry feedback?
      • 1” cubes needed (2-3 weeks)
      • Preferred field?
      • 12 polarization validation cubes needed (Mark will send them to Juergen)
    • VLASS data in archive
      • No good NRAO API to automate downloading of VLASS data
        • NRAO is working on an archive-wide API that would support VLASS
      • RA and DEC storage in the archive is not consistent in all epochs; improvements made in 3.2 such that scans track changes in RA, DEC
        • Mark will talk to John Tobin
