Hello all,
(Apologies for the cross-posting, but I know there are a good
number of Find_Orb users on MPML who aren't on the Find_Orb mailing list.)
I've heard from several people who ran into a problem in which
Find_Orb ignored any observation made after 2016 January 1.5. You may
not run into this problem, and even if you do, you can just work around
the problem without much trouble :

However, the bug has prompted me to post an updated Find_Orb that
includes a fix to this, plus a long list of small improvements and
accumulated fixes :

Also included is (at last) a 64-bit Windows version of Find_Orb. There
was a lot of hype when 64-bit processors first came along, but for
math-intensive software such as Find_Orb, some of that hype had real
merit, and you should see a boost in performance here. (A 32-bit version
is also available.)
Possibly the biggest advantage of the new version is the ability to
use the FCCT14 debiasing scheme :

Some other improvements in this version were listed in the "development"
version documentation, at
