| MTR2 spectrograph has an effective Resolving Power, R, of 300 000 to 400 000, mainly limited by the entrance slit width. Typical spectral resolution of MTR2 for a 0.5 arcsec slit width for different lines are:\\ | MTR2 spectrograph has an effective Resolving Power, R, of 300 000 to 400 000, mainly limited by the entrance slit width.
