  • Attached - CASA Documentation: proposed changes to documentation structure (simplification CASA Docs online & packaged; inline help). For discussion at Wed stakeholders meeting, feedback welcome.

Build, Release

Verification Testing

Validation Testing


  • Dave fixed test_imhead failure
  • Dave is working on test_imcollapse failure (apparently also a failure in the CASA 5 test suite which went undetected)
  • Finished script to create dynamic loader closure for casatools python module
  • Will look into building modules with manylinux Docker image


  • IDIA frontend, NRAO backend hosted on ASIAA server
  • NRAO development team: Patrick Brandt, Pam, Darrell. NRAO interactive testing: Juergen
  • CARTA Backend Development Confluence page
  • Current status:
    • Loads raster images in CASA, FITS, HDF5, and MIRIAD formats, displays default channel 0 and stokes 0. One image displays at a time.
    • Shows image histogram ("Render Configuration") for current channel/stokes
    • Shows image spatial profiles (X and Y) for cursor position and current channel/stokes
    • Animator cycles through channels or stokes and updates image, histogram, and spatial profiles
    • Interpolation, data compression, and histogram calculations have been parallelized for performance
    • Asynchronous message handling for communication with frontend
    • Spectral profiles are sent from the backend but not displayed in the frontend yet.
  • Working on:
    • Animation can cause backend to crash, possible threading problem in casacore
    • Message queue to prioritize and cancel backend tasks
