[time-nuts] More Allan deviation data

[Ulrich Bangert]

Hi Didier,

you may use the DRIFT section of the graphic editor of PLOTTER to remove
a phase drift due to a constant frequency offset as seen in this data,
with the result that you get more "visual resolution" out of it, as in
the attached PDF.
