Data Analysis Plugins#
Note
This is the config-specific version of documentation and is deprecated. See the general documentation for the most up-to-date information.
The Mosviz data analysis plugins include operations on both 2D images and Spectrum one dimensional datasets. Plugins that are specific to 1D spectra are described in more detail under Data Analysis Plugins. All plugins are accessed via the plugin icon in the upper right corner of the Mosviz application.
Metadata Viewer#
This plugin allows viewing of any metadata associated with the selected data.
If the data is loaded from multi-extension FITS that contains a primary header, you will also see a Show primary header toggle. When enabled, the plugin will only display the primary header metadata.
Export#
This plugin allows exporting the plot and/or subsets in a given viewer to various formats.
Plot Options#
This plugin gives access to per-viewer and per-layer plotting options.

Redshift Slider#
As in Specviz, the Line Lists Plugin includes a slider to adjust the redshift or radial velocity. In Mosviz, this is applied to the current row in the table and is stored (and shown) in a column of the table.
Warning
Using the redshift slider with many active spectral lines causes performance issues. If the shifting of spectral lines lag behind the slider, try plotting fewer lines. You can remove lines from the plot using, e.g., the “Erase All” button in the line lists UI.

Slit Overlay#
A slit can be added to the image viewer by opening the Slit Overlay plugin and clicking the Apply button. The Remove button can be used to remove a slit once it has been applied to the image viewer.
In order to plot a slit onto the image viewer, we need WCS information from an image and slit position from a 2D spectrum.
The slit position is calculated using the S_REGION header extension value, located in the
meta attribute of the Spectrum object
that is active in the 2D spectrum viewer.
