Sadly that is not what is measured. The returned
frequency is higher than expected suggesting the
carft is being slowed, hence the acceleration is
directed towards the Sun as stated in the abstract.

There is some fuzz on this in the literature  to wit:
You recall that from The Apparent Anomalous etc. by Turyshev et al 9
Mar 1999 where in the footnote on page 3 they say Dnu=nu - nu0 where
nu is the measured (rec'd?) frequency and nu0 the reference and cite
the value -6x10^-9Hz one way. In my case nu = low and nu0 would be
high so I get a negative result to agree with theirs. Then they put in
the questionable remark m/l saying would be negative for a station
approaching the station (blue shift) JUST THE OPPOSITE OF THE USUAL
CONVENTION.
I get the idea they had in their mind some extra gravity from the Sun
as the cause,  and adopted this backward convention.


No JPL always use that convention. I believe it may
be because positive values apply when the craft is
moving away from Earth, the usual condition, but the
real reason may be lost in the mists of time. Anyway
it is a convention that has been in use for decades
and all the JPL software expects it.

Anyway, a number of people queried that which is why
they added the explanatory confirmation.


At the risk of inviting the devil, Aladar Stolmar was one of the people who queried it. He also believed that the Pioneer effect genuinely was a red shift, and he was also confused about the difference between real years and light years :-)
