| The
Anglo-Australian Planet Search (AAPS) is a
long-term program being carried out on the 3.9m Anglo-Australian
Telescope (AAT)
to search for giant planets around more than 240 nearby Solar-type
stars with
V<8. We use the "Doppler wobble" technique to search for these
otherwise invisible extra-solar planets, and achieve the highest
long-term precision demonstrated by
any Southern Hemisphere planet search. |

UCLES Slit
Area - Automating the I2 cell
The I2
cell used to
sit between SF1 (slit filter wheel 1) and the entrance to the
UCLES
spectrograph room. In order to mount it in this location, SF2 (slit
filter
wheel 2) had to be removed. As part of the SuperAAPS project (and
funded by a PPARC grant) the iodine cell has been moved into a new
barrel mounted on the focal modifier wheel (which sits in between the
back of the slit and the SF wheels.
In this location, the insertion of the cell is now under control from
the UCLES ODC interface. No more running up and down the stairs to
insert and remove the cell when doing templates. Hooray!
It has now been used in this location for 4 months (as at April 2007)
and we have had no problems with using it there.
