s during the Astro-2 mission. The spectrum
covers 820-1840 Å with a resolution of
Å. The intrinsic
far-UV continuum is unattenuated to wavelengths as short as 920 Å (
Å in the galaxy's rest frame) and can be fitted with a power law with
after a correction for E
.
The power law fit to the far-UV continuum of Fairall 9 may be extrapolated to
connect to the soft X-ray component measured with ROSAT, forming a weak UV
bump. Photoionization by such an energy distribution
would produce relatively weak high-ionization lines.
The intensity ratio of the broad component (FWHM
) of O VI
1034+Ly
emission to that of C IV
1549 is
.
While this is typical for high-redshift quasars, it is
one of the lowest among the low-luminosity, low-redshift AGN observed by
HUT .
A correlation between the strength of O VI emission and the soft X-ray
excess is supported by the observations of Fairall 9 and other AGN.
