Description:
This is a study of the UV variability of the galaxy Fairall-9 between
1978 and 1991. Table 1 shows the UV continuum fluxes measured in three
"line-free" windows centered at 1171, 1400 and 1910 A (observed
wavelengths), and corrected for E(B-V)=0.035 extinction. The IUE Fine
Error Sensor (FES) counts (optical photometry) are also given in this
table, corrected for the same extinction.
Tables 10, 11, 12 and 13 show the variability of the components for
the main UV lines (Ly{alpha}+NV, SiIV, CIV and MgII). Line profile
variability has been used to isolate four gaussian line components,
which are sufficient to describe all lines at all levels of brightness
in a consistent way: one narrow (i.e. unresolved at the IUE
resolution) and three broad components: a central (velocity same as
the narrow line), a redshifted (v=3300 km/s) and a blue shifted one
(v=-3600 km/s). The Ly{alpha}-NV blend is fitted together in the
Ly{alpha} region (Table 10), to account the NV presence (one narrow
and one red component). The results for SiIV are shown in Table 11. In
CIV (Table 12) have been included a very weak component bluer than the
blue component, most likely associated with NIV] 1486. Table 13 shows
MgII results.
