I asked at the time but you said you hadn't
recorded it. Anyway I see no point in wasting
more time on it since the Pioneer data eliminated
the possibility.

I agree, the anomaly is more likely to have
a mundane explanantion.

Possibly but you need a correction that gives
a linear error while your gives a phase error
on the diurnal term. The characteristics are
completely wrong.

If your code can't read the data when everyone
else can, that's your problem. I even sent you
a copy of the data in Excel including my code
used to read the files as a macro. You could
have used that and stepped through to make sure
there was no trickery but you prefer to have an

I make neither of those assumptions. Both
affect the magnitude of the diurnal, not
the phase.

I made no such assumption, I posted the
calculation of the amount of error
introduced by the orbital motion for a
worst case alignment and showed it was

That again affects only magnitude. The
results showed you had a discrepancy of
about 26 degrees (IIRC) in the location
of the craft measured from two sites on
the same day with a worst case systematic
error of less than 1 degree. That ruled
your model out.
