dvsg calculates the kinematic disturbance parameter ΔV⋆−g (pronounced 'DVSG'), which quantifies the offset between the stellar and gas velocity maps of a galaxy obtained via integral field spectroscopy (IFS). The motivation behind ΔV⋆−g is to capture disturbances in the kinematics of a galaxy that might be missed by alternative methods, while also attempting to minimize bias towards any galaxy properties or features of the IFS data. dvsg provides lightweight functions to compute ΔV⋆−g, visualize results, and work with data from the Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey on which it was developed.
