[evlatests] Ku band status

[Ken Sowinski]

There are Ku band receiver at ea10, ea12, ea14, ea20, ea22 and ea24.
Collimation pointing was checked today and all but ea14, which was
too far off to give good pointing solutions were adjusted.  A coarse
collimation adjustment was made for ea14, but more work is needed.

Delays were set when each receiver was first commissioned, but have
not been looked at with any care since then.  Focus has been set and
checked only haphazardly.  Ku band will have to be added to the
focus checking script sometime soon.
