Descripción
We discuss the multi-Gaussian decomposition of the [O III]
λλ 4959,5007 emission line profiles from 2-D spectroscopy.
We found that a model based on five main gaseous components can
reproduce the observed line profiles consistently. The morphology of the
intensity maps of some of these gaseous subsystems seems bipolar. This
is in better agreement with current ideas about the alignment of the
ionization in AGNs than the relatively amorphous morphology seen in
filter images. The centre of the inter-pole region is sited ~ 2″
NE of the optical nucleus, close to the origin of the strong outflow of
ionized gas recently reported (Arribas et al. 1996). This suggests that
the putative hidden nucleus of NGC 1068 could be sited near to this
point.
