ISMgas

ISMgas is a python module used to analyze absorption line kinematics of Interstellar Medium gas. The module takes a 1D spectra as an input and extracts key kinematic diagnostics (such as velocity centroid of absorption) by fitting the absorption profile with multiple gaussian profiles.

Installation and development

git clone https://github.com/kvgc153/ISMgas.git
cd ISMgas/
conda create --name ISMgas 
conda activate ISMgas 
sh setupISMgas.sh
