Previous: 8.3.3 Time and THDA
A check of the SWP high-dispersion wavelength calibration was made
against the Copernicus satellite wavelength system for the
standard B0.2 Scorpii with representative large-aperture images.
This check showed a zeropoint offset of -4 km/s with respect to the
Copernicus system for typical images; no trend with wavelength was
found. The estimated errors in the IUE wavelengths as measured from
these Scorpii observations were ±5 km/s per line.
