of turning and I missed Agena BUS ARM EXPERIMENTS
and I missed jettisoning the door on the cold IR.
That's my fault and I jettisoned the door on the
cold IR at 02 hours , 16 minutes, 15 seconds after
liftoff. I started taking the first REP measure
ments and unfortunately it was at 2500 feet. I
felt that it was still readable so that is where
the data starts. We got some black sky along side
the REP with the cold IR. The radiometric and
IR spectrometer alinements were r ight on the
button . So was the cold IR. We had no trouble
with the power down procedures. It was very
straightf orward. We never did get to do the
cryogenic gas lifetime updates . We never got
the Milky Wey with that cooled sensor. We did
get the void black space with the cooled sensor.
We got the Zodiacal light . We got most of the
star .measurements . We got the moon. We got the
night land measurements. No, well,· we got the
numbers that I mentioned. I just don ' t remember
all of them. I did not get a:n:y cloud illumination
with lightning. I did get dey land measurements .
I got the Ascension calibration. I got an IR cloud
blanket sweep , but I did not get the cumulus clouds .
