Data Analysis Plugins
The Mosviz data analysis plugins include operations on both 2D images and Spectrum1D one dimensional datasets. Plugins that are specific to 1D spectra are described in more detail under Specviz:Data Analysis Plugins. All plugins are accessed via the plugin icon in the upper right corner of the Mosviz application.
Gaussian Smooth
Gaussian smoothing of a spectrum is described under Specviz:Data Analysis Plugins:Gaussian Smoothing.

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 Spectrum1D
object
that is active in the 2D spectrum viewer.
