SUMER Results

The following data files (Lalpha_Jul1996_27.data, Lbeta_jul1996_19.data ...) provide the provisory spectral irradiance distribution in H I Lyman alpha and beta profiles obtained with SUMER at the date of each file. The data are obtained from the scattered light of the SUMER telescope and calibrated with the SOLSTICE/UARS H I Lyman alpha irradiance. The data reduction procedure is described in: Lemaire, P., Emerich, C., Vial, J.-C., Curdt, W., Schuhle, U., Wilhelm, K., 2002, ``Variation of the full Sun hydrogen Lyman alpha and beta profiles with the activity cycle'', to appear in the proceedings of the conference SOHO-11: From Solar Minimum to Maximum, ESA SP-508.
