IMACS spectral atlas
Longslit HeNeAr arc spectra for the main IMACS dispersing elements
You may find the following FITS files useful for reference or
planning. They each contain a wavelength-calibrated 1-D spectrum for
one of the main dispersing elements available on IMACS at f/2. These are
also available on the data disks on both observer workstations in the
Baade dome at:
