Allegro Software Inventory

Scientific exploration of ALMA observations does not stop when an image is produced: there exists a wide range of tools that can be used to further explore your ALMA data, plot and inspect parts of your ALMA data, and compare your ALMA data to models of astrophysical objects. Many of the tools that are developed by the scientific community are publicly available.

To help ALMA users navigate the many options and find tools that they may not even know exist, Allegro, with the help of the European ARC node network, has developed an interactive inventory to ALMA-related software. This inventory is not intended to be complete and will always keep growing. If you know of useful tools to be added, or find an inaccuracy, please contact us at

For each piece of software we list the name of the piece of software along with a link to its website, a short description taken from the software's website, a description of experience with the software within the European ARC nodes, a list of tags for the software and notes about the software. More information about the European ARC Nodes experience field and the Tags field is provided below.

European ARC Nodes experience

For each piece of software in the catalogue, a descriptor of the current status of how recently experience has been reported with the software by staff in the European ARC Nodes is given in the “Status” column. The different statuses are as follows:

  • Recent experience (<1 year ago) at the European ARC nodes
  • Experience 1-2 years ago at the European ARC nodes
  • Experience >2 years ago at the European ARC nodes
  • No or limited experience at the European ARC nodes

These colour codes are modelled after the ski piste rating system. Staff at the European ARC nodes are less likely to have experience with software with a status further down this list. The experience level does not reflect the usefulness of the code, or if it will run on current platforms. Even codes that no one at the European ARC nodes has experience with, may work perfectly and be just the tool you are looking for!

List of software

This is a searchable and sortable table of software listed in the software inventory. Click on the arrows next to column titles to sort by that column. You can also use the search box to filter the content, for example try searching Working recently to see only working software that is listed as working recently. Software is also tagged with a number of properties that you can search by, for example try searching #visualisation to see software that can be used for visualisation.

The full list of tags is: #analysis, #archive, #calibration, #CASA, #datacubes, #FORTRAN, #GILDAS, #GPU_computing, #imaging, #kinematics, #modeling, #modelling, #moments, #observing, #polarisation, #polarization, #python, #simulation, #virtual_reality, #visibilities, #visualisation, #visualization, #VLBI, #VR

There are currently 59 pieces of software in the repository.
