The cover assembly was installed at the end of December 2006. It is
made from insulated foam and shields
the spectrograph from thermal turbulence within the
chamber, reduces stray light and protects the mirrors from dust.
It is now expected that the thermal stability of the spectrograph
will be better than 0.01°.

Two sides of the cover (right side and back) can be opened for access to SOPHIE.
The cables running on the ceiling, on the floor and hanging on the extreme
right gather data from various temperature sensors installed outside and
inside the cover.
