Three
calibration
proposals
were
executed,
one
to
monitor
the
UV
throughput
and
focus,
one
to
measure
the
flat­field
linearity
characteristics
and
another
to
verify
the
aper­
ture
location.
All
proposals
executed
successfully.
.
The
aperture
location
for
the
f/96
relay
is
at
(V2,V3)
=
(242.9329,135.2735)
based
on
the
recent
astrometric
observations,
compared
with
a
position
of
(V2,V3)
=
(242.9714,
135.2052)
as
given
in
the
PDB.
The
scatter
in
the
observed
positions
of
the
stars
provided
a
mean
positional
error
of
only
0.10''
in
the
aperture
reference
position.

(cont'd)

The

is
scheduled
to
be
re­activated
on
Day
304
(Oct

This
reactivation
will
attempt
to
locate
the
F/48
long­slit
aperture.
This
proposal
will
be
a
3

proposal
in
order
to
avoid
any
possible

noise
from
the

as

UV
Throughput
Monitoring:
This
proposal
ran
on
day
1994.273.
Evaluation
of
PSF
quality
shows
that
we
have
experienced
a
significant
change
in
focus
since
this
test
was
last
run
on
day
222,
probably
due
to
desorption.We
have
a
DOB
movement
scheduled
for
the
297
SMS,
and
no
FOC
activities
(Calibration
or
Science)
between
now
and
then.
Data
from
the
past
2
weeks
will
be
examined
to
determine
the
DOB
correction
needed.
UV
throughput
appears
nominal.

SPACETELESCOPESCIENCEINSTITUTE FOC
DQE
Measurements
­
progress
report
Observations
of
spectrophotometric
standard
stars
have
been
used
to
verify/refine
the
FOC
DQE
calibration.
Due
mainly
to
the
aperture
size
used
for
flux
normalization
com­
pared
to
pre­COSTARmeasurements,
there
is
a
~20%
lower
throughput
in
the
far
UV,
with
a
roughly
linear
relation
between
the
expected
(i.e.
CDBS)
DQE
measurements
and
the
actual
values
measured
with
the
newer
normalization.
Tied
in
with
this
is
the
determination
of
the
actual
transmissions
of
the
ND
filters,
since
a
variety
of
such
filters
are
used
in
the
DQE
calibration.
Comparison
ofmeasurements
with
a
particular
ND
filter
with
those
without
do
not
show
any
significant
bias
due
to
ND
filter
transmissions
incorrectly
specified
in
the
CDBS,
although
other
independent
measure­
ments
of
ND
transmission
do
appear
to
show
some
discrepancy.
This
situation
is
still
under
investigation.
