On this page, we provide information and downloads for the CGWAS hands-on sessions each afternoon. You will need to be set up with the CGWAS virtual machine. You can find information on how to do this on the CGWAS computing page.
Many of the exercises will likely involve some basic numerical computing and plotting with Python. The Caltech Ay190 Computational Astrophysics Notes contain a brief introduction to Python and a discussion of and reference for basic numerical methods.
Important: One additional piece of software must be installed
on the virtual machine for this to work. It's easy. Open a terminal, then type
sudo apt-get install lalframe-python and enter
as the password. This should do the trick.
