Tom,

As always.

OK. I'll see what I can do. I beleive I already have something, but I think I
will have to massage it to do anything but ascii-tables.

The phase and frequency offsets will naturally be canceled out by ADEV and
MDEV. It is interesting to plot compensated and non-compensated data alongside
each other with the drift there too.

What do you use for generating the plots? GnuPlot?

Cheers,
