During Cycle 1, Pictor A was observed through the F517N and F547M filters on
Sept. 12, 14, 15, and Oct. 8, 1991.
The F517N filter covers the emission lines from [OIII] 
4958 and 5007 while the F547M filter includes these emission lines
at its blue end but also transmits roughly five times more continuum
emission than the F517N filter.
Our objective was to separate out the NLR from the continuum emission
by subtracting the different filter images.
During Cycle 2, Pictor A was observed through the F648M and F718M filters on
Sept. 20, 1992.
The F718M filter covers the emission lines from H
, 
6563,
[NII] 6527, 6548, 6583 and [SII]
6717, 6731, while the F648M filter
only includes the [OI] emission lines at 6300, 6363
which appear in the ground-based nuclear spectrum at a factor
of 
20 less intensity than the H emission line.
Again our objective was to separate out the H + [NII] emission line
regions from the continuum emission.
These observations had the obvious drawback that the true, observed PSF
for this object would have an ``effective filter'' which was a function
of the relative emission-line strengths at each point and their
redshifted wavelength. However, this is a secondary effect compared
with the aberration problem.
