===Setting up the grating===
Note that the wavelength ranges and resolutions listed in the table below are only approximate, the new values are still to be determined from the recent instrument commissioning data! The angles listed in the right hand column of the table are just to get one into the range where lines are visible for a given grating. One then needs to adjust the grating angle to obtain the desired wavelength range - consult the arc maps in the old spectrograph user manual (a hard copy is available in the warm room).
