Calibration of the GHRS . The GHRS has a spectrum calibration lamp which is used by specifying SC2 as the aperture with WAVE as the target. ... The lines are bright enough so that a 30 to 60 second exposure will yield a good comparison spectrum at almost any wavelength, although longer times are needed at some echelle settings. ... Also, wavelength calibration exposures are generally used to just confirm the zero-point of the spectrum and not to obtain a full wavelength solution. ...
