Background
Given a DEIMOS image acquired with a mask in place, the DEIMOS
Plotmask widget allows observers to generate plots of their
slitmasks annotated with selected information on the targets
assigned to each slit. This is useful for determining which
slits in the spectra correspond to which targets.
Invocation
To launch the widget from the DEIMOS background menu, select
DEIMOS Utilities > DEIMOS Plotmask Widget. After
a few seconds, the IDL
Virtual Machine banner will appear. Click this, and the
widget will run.
Usage

Navigate to the directory with the DEIMOS images and select an
image to plot it.
