    I tried also OD on my side and found :

I get slightly better residuals with different e and aop (sdp4 model). It gives
significantly different  trajectories everywhere except around southern apex,
where observations are done. To solve the ambiguity, points with higher 
declination are needed.

A strange behaviour of the time residuals, could it come from the long time
exposure uncertainties (Yeong ?).
