His report: I have processed a number of ODR's which were acquired after the spacecraft began to slew off point at or before occultation ingress. I do not believe that any of these are useful for science. Dave can look at them if he likes. I used SPK files for steering the data. SPK predicts are fine if the goal is only to see if there was a sawtooth problem or not. Some of the egress occultations could not even be steered, however, due to very low signal level. For these ODR's, it is not possible to determine if there is a sawtooth problem or not. Some other egress ODR's were steered but still did not process to completion due to low signal level. I did not see any sawtooth problems in the ODR's (at least in the ones that were steered). I am still waiting for trajectory reconstructions from Goddard before processing the data from occultations #119 (4/6) through #142 (4/17). 81082221 Occultation #144 ingress 81082255 Occultation #144 egress Not steered 81091002 Occultation #145 ingress 81091034 Occultation #145 egress Not steered 81092147 Occultation #146 ingress 81092214 Occultation #146 egress Not steered 81100922 Occultation #147 ingress 81100953 Occultation #147 egress Not steered 81102106 Occultation #148 ingress 81102132 Occultation #148 egress Not processed to completion 81110841 Occultation #149 ingress 81110913 Occultation #149 egress Not processed to completion 81112020 Occultation #150 ingress 81112050 Occultation #150 egress Not processed to completion 81120801 Occultation #151 ingress 81120828 Occultation #151 egress Not steered 81121938 Occultation #152 ingress 81122007 Occultation #152 egress Not processed to completion Closed Loop Data ================ Data Collection --------------- No new data.
