Bellow is a list of existing mask plates for the MTR2 spectrograph. A mask plate is identified by its number, with its corresponding observation wavelength and possibly information about the lines of interest. The final spectrogram will have a ~6-7 Å passband around that wavelength, hence with eventual multiple lines of interest.

Observers wishing to have a known working set-up can directly request one of these masks. New mask plates can be requested/designed but the observer shall verify that the requested set-up is feasible.
