I used the 8089121A.SPK file to steer it. I believed that SPK file should contain a reconstructed trajectory for the occultation in question. The ODR suffers from the sawtooth problem. I have seen this in 4 of the last 13 ODR's that I processed. Just to remind you all: Occ #92 80831600 Occ #97 8086022D Occ #100 80871320 Occ #104 80891159 One other problem: there is an offset in the steered data for occultation #104 of about 6 Hz from the center of the band. This does not make sense to me, unless the SPK file is not actually a reconstruction of the trajectory for that orbit. The SPK start time is 98/089-01:25:00 which is actually during the egress recording for the previous occultation.
