[evlatests] ea16

[Ken Sowinski]

Eric reported that ea16 is in good enough shape to try.

Fringes were obtained at C, X and Ku bands.  X band was
quite a bit worse than both C and Ku bands.  I suspect
T_sys, but pointing is sufficiently uncertain that part
of the problem with X band may be collimation.

C band pointing will be done before Monday.  After that
we will try X band again and look at the high frequency
bands.
