From earlier
proportional counter
|
|
|
observations,
Seyfert 2 galaxies were
|
|
|
found to be much
more highly absorbed
|
|
|
than Seyfert 1s,
but not much else was
|
|
|
known about the
details of their spectral
|
|
complexity.

The prototype
object in this class was
|
|
|
observed with
BBXRT and found to
|
|
|
exhibit discrete
residuals, but the
|
|
|
spectrum proved
difficult to interpret.

Marshall claimed
a significant
|
|
|
underabundance of
oxygen.

ASCA provided a
much higher quality
|
|
|
spectrum,
exhibiting narrow Fe K
|
|
|
emission, and a
host of lower energy
|
|
|
features.

Ueno interpreted
this in terms of a
|
|
|
power law
continuum, with an
|
|
|
additional
thermal component at low
|
|
|
energies due to
starburst activity.
