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. WCS information is taken from the meta
attribute of the CCDData
object representing the data in the image viewer. The slit position is calculated using the S_REGION
header extension value, located in the meta
attribute of the SpectralCube
object that is active in the 2D spectrum viewer.
