# arts-cat
The steps required to generate Artscat, the absorption line catalog of ARTS
This is the software used to generate Artscat, which is available as supporting data to ARTS (www.github.com/atmtools/arts)
The intent of this project is to curate Artscat and to continuously provide updates to various parameters within it.
# Usage
python arts-cat.py path/to/hitran-file
