Mechanical |
- CCD mount: rotation adjusters have to be fitted to make alignment more
repeatable and less time consuming
- Fit a CuAr lamp on the gripper arm. This allows to do tests on
calibration in the blue, having the light source closer to the fibres.

Optics
|
- Wyffos optics: big mirror needs cleaning. The small relay mirror needs
recoating. The spare has been aligned. It has a slightly smaller radius. It
was agreed to put the spare in the next run 7th november and check if it is
usable, if so we leave it in and send the original one away for recoating.
- Wyffos ghost: ghost has been identified with a calibration lamp. A
temporary baffle was fitted. This solution is at the cost of losing light in
the blue part of the spectrum. Investigation on having a dynamic system that
is only operated during calibrations. see fault

Electronics |
- The WYFFOS calibration unit has been overhauled in 2010. The
clutches and redundant cables have been removed. A 4th lamp (Hg) has
been fitted.

Computing |
- AF2pc strategy: Both pc's are always on the network. This to make sure
that both machines are kept up to date. The machine that boots up last takes
control of the instrument. If there's a failure on the af2pc you should
change to the other af2pc. (see instructions)
