Subject: SUMER-SOFT: S VI 933A line blend

    Dear SUMER spectroscopist,

    We have dealt for some long time with the exact position of the S VI
    line at 933.38 A und found some unexplainable redshift in all the data
    we examined.  It appeared that the line center was always found above
    933.4 A no matter at which location observed, on or beyond the disk.
    We now think that this redshift is due to a blend with the Balmer-13
    line of the He II Series.  From the Balmer-11 and -15 lines,
    which we can indentify in the spectra and which seem to be unblended,
    we can estimate that the contribution of the He II Ba-13 is about 15%
    of the total intensity at 933.4 A.

    Best regards,
    Werner & Udo
