Uncertain sequences (was Re: TR : Re : The OEIS will be on holiday for the rest of the year!)

[N. J. A. Sloane]

Jaap Spies says:

There is another uncertain factor in the calculations and that is
the planetary model. Some calculations use the VSOP 87 model and
others depend on the JPL ephemerides from NASA.

What policy do you have with sequences that may be changing in time?



Me:  in general they should be avoided, of course.  But if there
is a published version, then that could be included.  Even if later
it were to change.

Just as we have A008578, primes at beginning of 20th century.
