Setting Redshift/RV
The Line Lists Plugin contains a redshift slider as well as the ability to view and set the redshift and/or radial velocity.
From the notebook
In the notebook, the value of the Redshift column can be changed for all rows or a single row
using update_column().
The 1D and 2D spectrum objects can be retrieved (with redshift optionally applied) using
get_spectrum_1d() and get_spectrum_2d(),
respectively.
