Hi Jiaan. I recommend using the arts-cat-data package we provide. It is available at https://www.radiativetransfer.org/tools/ under the heading ARTS Catalog Data. I have added Zeeman effect and line mixing of O2 to those lines (the exact changes are in my repository at https://github.com/atmtools/arts-cat). They should be otherwise very similar as to what HITRAN provides. It might only work on a newer version of ARTS (which you can install easily if you use conda-forge following our guide at https://atmtools.github.io/arts-docs-master/installation.html).
