[evlatests] Strange Tcals and Switched Power behavior

[Ken Sowinski]

I used Barry's utility to examine L band Tcals.

If Rick happened to look at a subband tuned near 1000 GHz, then the
recorded Tcals are indeed a few tens of K.  I verified that Tcals
for ea24 are all around -24 K.  Correct values will have to be found
and inserted into the database.
