This

caused
by

Two

observed,
both
suffered
from
binary
acquisition
failures.
The
targets
PKS0254­334
and
Q0254­334
exceed
that
``maximum
error
1
arcsec''
statement
in
the
handbook
regarding
the
target
positional
accuracy.
PKS0254­334
was
off

by

The
target
was
not
found.
This
is
a
snap

with
blind
pointing.
GO
did
not
want
to
spend
time
(20min)
to
acquire
the
targets
with

have
5min
exposures.
The
GO
does
expect
30%

acquisition
failures.
