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:

/Volumes/Data_Llama/Backup/Calibrations_and_Tools/IMACS/IMACS_arcs/

/Volumes/Data_Burro/Backup/Calibrations_and_Tools/IMACS/IMACS_arcs/

Click on the figure title to download the actual FITS files containing the spectra. The figures are meant as a quick reference guide only. You can view them close up by right-clicking and selecting "View image" or "View image in new screen/tab" (in most browsers).
