2025-11-27: New Major Release (4.6)

A new major release (Nov-2025, 4.6-03) is available for Linux (Apptainer binaries) and for compilation on Linux & MacOS

It corrects a major issue in Mosaics (mosaics with different phase centers were not treated correctly), so it is recommended to install it for a fully fonctional version for all users.

MacPorts version will come as soon as possible.

2025-05: New demo scripts

New interactive demo scripts are available.

This includes the following possibilities:

  • simulate (setting up an ALMA simulation)
  • polar (handling polarization data)
  • advanced (spectral line cases: imaging with continuum and multi-scale spectral clean)
  • selfmosaic (selfcal demonstration on a spectral line case for a Mosaic)
  • restart (continuum + spectral line case using CLEAN /RESTART option)

Just type @gag_demo:demo to start with, and enter your preferred demo name at MYDEMO = to get it running.

2025-05-15: New Major Release (4.5)

The new version (4.5-01, April 2025) is now fully available for installation on Linux, Windows and MacOs (including a MacPorts package).

Version 4.5 is a critical release. The major improvements include:

  • Self-calibration of Mosaics for multiple channels
  • More robust PIPELINE operation
  • Better noise estimate on data cubes (STATISTIC)
  • Methods GUETH and SAULT available for Mosaics
  • New engine for MODEL command using Clean Components
  • New engine for Self-calibration on very wide bands
  • Command UV_CONTINUUM is deprecated: UV_MAP /CONT and UV_FIT /CONT should be used instead

2024-12-12: New Major Release (4.4)

The new version (4.4-01, December 2024) is now fully available for installation on Linux, Windows and MacOs (including a MacPorts package).

Version 4.4 is a major release with numerous improvements compared to Version 4.2. The most significant changes are :

  • Full polarization support.
  • More tools to handle non regular and/or non contiguous frequency axes: see commands UV_MERGE, UV_LINEARIZE
  • Better handling for Proper Motion (a reference epoch can now be specified)
  • Better Multiple spatial scales clean with command GCLEAN
  • Improved SELFCAL for wide band data.
  • New REPORT command to prepare a PDF summary of an observation set, before and after the PIPELINE execution.
