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.

Additionally, the Line Analysis Plugin includes the capability to compute and assign the redshift based on the measured centroid of a line.

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.

See the notebooks/MosvizNIRISSExample.ipynb notebook in the repository to see examples of manipulating MOS Table data, including the redshift.
