When I saw the elset for 287.16 that Mike posted, I searched for the last
preceding one. That seemed to be old, but on CalSky I think they had one
around day 262 !?

So, I thought Mike's elset was accurate, and although I got 11 track images
that night, I didn't reduce them.
On second thought I believed that positions further north than latest obs
would be useful, so I reduced four of the track starts (#1,4,9,11), and
they had the following residuals :
Obs - Pred, relative 0.68 day old elset:
10,612 min X-track; 15,978 s late
10,075 min X-track; 16,160 s late
 9,355 min X-track; 17,053 s late
 3,535 min X-track; 15,753 s late

All offsets where on the S side of the track
