Abstract:
We present a reworked version of the SUMER spectral atlas (Curdt et al., 2001). New identifications are given for more than 100 emission lines; entries were corrected or added to the list. The solar emission curve - spectral radiance versus wavelength - in the SUMER spectral range is now available in digital format as electronic supplementary material. To reveal the true solar emission, second-order photons from the Lyman continuum have been discarded near the long wavelength section in the first order of diffraction.
