Install Common Astronomy Software Applications - CASA in Ubuntu 14.04, 16.04 and 18.04 LTS

[Eli]

CASA, the Common Astronomy Software Applications package, is a software that supports data post-processing needs of the next generation radio astronomical telescopes such as ALMA and VLA. CASA can process both interferometric and single-dish data. The package infrastructure consists of a set of C++ tools bundled together under an IPython interface as data reduction tasks. This structure provides flexibility to process the data via task interface or as a Python script. Read more>>>

Installation

CASA is continually being tested under Linux - Red Hat 7 & Red Hat 6, Mac OS X - macOS 10.13 (High Sierra) & macOS 10.12 (Sierra), but may also work on other distributions such as Ubuntu Linux.

To install CASA on Ubuntu Linux versions 14.04, 16.04 and 18.04 follow these steps:

1. Downloading the current release of the CASA code for your specific operating system (we will download release version for Red Hat 7)

2. Move to the directory where you downloaded the file ...tar.gz (casa-release-5.4.0-68.el7.tar.gz, in Downloads for our case) and then unpack it:

Code: [Select all] [Expand/Collapse]

1. $cd ~/Downloads
2. $tar -xzvf casa-release-5.4.0-68.el7.tar.gz

The binaries are pre-compiled, we just need to unpack them.

3. Make a symbolic link (also symlink or soft link) to it in a path location so that you can start CASA by typing "casa" from anywhere in the Terminal:

Code: [Select all] [Expand/Collapse]

1. sudo ln -s $HOME/Downloads/casa-release-5.4.0-68.el7/bin/casa /usr/local/bin/casa

You can however add the directory where the binary is located to your path instead of making symlink:

Code: [Select all] [Expand/Collapse]

1. export PATH=$PATH://casa-release-5.4.0-68.el7/bin

When you type casa from the Terminal, you should see something like this:
