Abstract (from CDS):

The laboratory wavelength calibration of the SWS has been succesfully transferred to the in orbit situation. The achieved accuracies for the grating sections are λ/δλ∼10000. Any remaining errors in the wavelength scale are dominated by uncertainties of the relative position of the target in the 14"-20" wide slits. The grating spectral profile is very well represented by a Gaussian shape. The width of the grating spectral profile can be accurately predicted by a theoretical model. The wavelength calibration of the FP's is accurate to within 1/3 of a resolution element, corresponding to λ/δλ∼105. The wavelength stability of the gratings and FP is excellent, no measurable changes were found during the first 6 months of the ISO mission.
