[evlatests] ea03 getting there

[Ken Sowinski]

It sort of works, but there are some problems.

C band is weird.  It is clear that the ploarizations are swapped.
Besides that the SD ratios are not right.  In the current, swapped,
state the IFs reported as AB show a SD ratio of ~0.02, while the
IFs reported as CD show a SD ratio of about 0.3.  I did not look
at the bandpasses.

Pointing is way off.  Much more than could be expected from the
pre-refitting pointing model.  An L band pointing run should help.

The X and K band receiver look OK, but not much more can be said.
