J/A+AS/113/237      Ultraviolet Spectrum of the Sun (Samain, 1995)

Description:
    An ultraviolet atlas of the solar spectrum with a spectral resolution
    of 15mA in the region 1948-2000A is presented. It is the first part of
    the spectra recorded on the quiet Sun between 1900 and 2130A.
    Measurements were performed from a balloon-borne instrumentation flown
    at an altitude of 39km. The wavelength atlas with a list of about 550
    lines has been synthesized from data at center of the Sun ({mu}=1) and
    at {mu}=0.89, smoothed out over an area of 30 arcsec.
    The wavelength scale is given with respect to the average solar
    spectrum. Tracings are presented at {mu}=0.89, with an intensity scale
    adjusted in absolute values on the level of the continuum near 2000A.

--------------------------------------------------------------------------------
Note (1): All wavelengths are given in the vacuum, according to usage
          below 2000 A. As underlined in the A&A publication, an average
          shift of 7mA is to be added to the measured value of the telluric
          lines for a proper comparison with their laboratory wavelengths.
Note (2): When 'a' these lines correspond to features not separated in the
          observed spectrum. When we tried to take these wavelengths as
          references in the wavelength tabulation, we have compared the average
          measured wavelength to the arithmetic average of the two laboratory
          wavelengths.
Note (3): Approximately representing the degree of absorption at the center of
          the line with respect to the intensity level outside of the line; 0
          is a line barely detectable.
Note (4): W: wide line(50-100mA)
          VW: very wide line(>100mA)
          b: blend
          d: double line
          e: emission line
          T: terrestrial O2 line(no indication = solar line)
          T*: terrestrial O2 reference line
          S*: solar reference line
          (S*)/(T*): solar/telluric reference line ejected
Note (5): Laboratory lines whose wavelength differences with our solar
          determinations are not lower than 10 m, have not been retained
          generally, unless the laboratory uncertainty exceeds that value
          or the feature observed is very wide. In the case of telluric
          lines, whose features listed here are all due to O2, notation of
          the transition is given instead of the name of the element. To point
          out the disturbed regions of the solar spectrum, we have reported all
          the laboratory wavelengths of known lines belonging to the O2
          Shuman-Runge system and encompassed by the spectral interval
          1948-2000. However, for many weak lines (like the bands 5-1 and 4-1)
          correspondence with observed values in the atlas is often given only
          for the record.
