A current list of gratings is given here . Grating numbers have been assigned in order of acquisition. Wavelength Parameters Calculators to estimate wavelength centre, coverage and dispersion for a given grating angle are available for 2dF and the RGO spectrograph . Note that slightly different parameters are used for the RGO at the telescope, but the differences are within the estimate error. For exact values, arc frames should be used.
Work is in progress to remeasure the grating set.
