The recording began 22 minutes before tracking was scheduled to start. Most occultations collected using DSS 15 show the 7 second carrier modulation that has been present for several weeks (see HEA2330A.TXT and ISA Z78518). Modulation is strongest at low elevation angles: Occultation Start Date/Time DSS Amplitude ----------- ----------------- --- --------- 16695i 2002/336-15:20:00 15 +/-0.2 dB 16697i 2002/336-19:15:00 15 +/-0.2 dB 16698e 2002/336-20:00:00 15 +/-1.0 dB 16698i 2002/336-21:13:00 15 +/-1.5 dB Carrier level decreased approximately linearly by about 0.5 dB over 6 minutes prior to ingress in data from occultation 16696i (DSS 15, start time 2002/336-17:17:00). Data collected from occultation 16702i at DSS 45 (start time 2002/337- 05:04:00) do not include ingress. The occultation occurred after end of tracking (05:00:00). Data collected from occultation 16705e at DSS 65 (start time 2002/337- 09:44:00) include only about 3 minutes of data after egress. Scheduled end of track (09:45:00) occurred before the recording was completed.
