The :ref:`Line Lists Plugin <mosviz-line-lists>` contains a redshift slider as well as the ability to view and set the redshift and/or radial velocity.
Additionally, the :ref:`Line Analysis Plugin <line-analysis>` includes the capability to compute and assign the redshift based on the measured centroid of a line.
In the notebook, the value of the Redshift column can be changed for all rows or a single row using :py:meth:`~jdaviz.configs.mosviz.helper.Mosviz.update_column`.
The 1D and 2D spectrum objects can be retrieved (with redshift optionally applied) using :py:meth:`~jdaviz.configs.mosviz.helper.Mosviz.get_spectrum_1d` and :py:meth:`~jdaviz.configs.mosviz.helper.Mosviz.get_spectrum_2d`, respectively.
See the notebooks/MosvizNIRISSExample.ipynb notebook in the
repository to see examples of
manipulating MOS Table data, including the redshift.
