Yes indeed; the soida file has an extra column containing Tcal*10
which was loaded instead of the proper column. Corrected.

The S band receiver in ea02 does not identify itself in monitor
data. MIB is pingable but appears unresponsive. Will fix Tcals
when receiver identifies itself.
ea12 - those are the numbers in the soida files in the 'Current' area,
and are about what they should be.

There are other soida files with numbers a factor of two (not four)
lower.
