After the wavelength calibration is obtained from a MOS arc lamp exposure, the
wavelength corresponding to the center of the CCD is computed (only if all
slitlets are in the center of the CCD). The
values trended here are for the 300V grism with a slit width of
1.0" and the order separation filter GG435.
Data have been acquired using the blue-sensitive EEV detector.
