Calculations regarding the back-scattering of different Wide Angle Baffle designs (Zeidler)
Personal calc of WAB's stray light noise by Akutsu; due to several uncertain parameters there are several results and no one would know the actual effect!

Task list
Note: some of the tasks can be done in parallel.
Place/install the WAB suspension
Align the position of WAB -> take WAB back to nominal position, put off protectors)
horizontal alignment
yaw alignment
Move it to the saving mode.
Back to the nominal position.
Attach heat links
4 soft heat links to WAB
1 heat link btwn the top and the structure
Attach 2 thermometers
- Set revised blocks under the base plate.
Pin Assignment

Note that the pin arrangement (or the naming) is mirrored compared with that of in IXC! Rather, I guess this IXC's would be correct.
