COS Walkthrough Notebooks
The Cosmic Origins Spectrograph (COS) team has created a series of interactive Jupyter Notebooks to walk users through common procedures for working with COS data products. These notebooks are intended for COS users of any experience level. We encourage you to use them, adapt them, and share them with your peers, colleagues, and students.
They can be accessed through the spacetelescope/hst_notebooksGitHub repository in the subdirectory notebooks/COS, as well as in the table below of currently operational notebooks.
Please visit the COS Notebooks website for additional details on installation, setup, and updates.
You can also view our iPoster from the 238th conference of the AAS.
