Aseel Anabtawi is investigating and the measurements should be included in the next report. All measurements from DSS 34 occultations 14241i through 14244i (start times 2002/136-00:58:00 through 06:51:00) had SNR levels 3 dB lower than expected. Data collected from DSS34 occultation 14244i (start time 2002/136- 06:51:00) had a -1 dB notch in the carrier amplitude lasting about 30 s and beginning roughly 2 minutes into the measurement. The following occultations had changes in the noise level shortly after ingress: Occultation Start Date/Time DSS # Amplitude Secs after ING ----------- --------------- ----- --------- -------------- 14241i 2002/136-00:58 34 + 1 dB about 108 s 14255i 2002/137-04:26 45 - 1 dB about 90 s Closed Loop Data ================ Data Collection --------------- We have obtained the following files from OSCAR and EPIC: Original File Name Name on SOPC ------------------------------------ ------------ TDF: 02111T113.DAT;1 2110113A.TDF TDF: 02113T114.DAT;1 2113114A.TDF TDF: 02114T116.DAT;1 2114116A.TDF TDF: 02116T118.DAT;1 2116118A.TDF TDF: 02118T119.DAT;1 2118119A.TDF TDF: 02119T121.DAT;1 2119121A.TDF TDF: 02121T123.DAT;1 2121123A.TDF TDF: 02122T124.DAT;1 2122124A.TDF TDF: 02124T126.DAT;1 2124126A.TDF ODF: 02136O137_10S.SJO;1 2136137A.ODF TRO: ATC02MAY.CSP;6 2121139A.TRO EOP: 020517-eop.long 20202220.EOP EOP: 020517-eop.short 12192220.EOP Ancillary Data ============== Data Collection --------------- We have obtained the following files from the FIS: Original File Name Name on SOPC ------------------------------------ ------------ AMD: amdgen.02-137.out 2135136A.AMD DKF: mm179a.07.dkf 2139143E.DKF DKF: mm180a.03.dkf 2142146A.DKF SAK: mgs_solar_array_2002-135.ck 2135135A.SAK SOE: mm179a.07.tsoe 2139143E.SOE SOE: mm180a.03.tsoe 2142146A.SOE TCK: mgs_spice_c_kernel_2002-135.ck 2135135A.TCK We have obtained the following files from NAIF: Original File Name Name on SOPC ------------------------------------ ------------ AGK: mgs_hga_ck_2002-05-07.bc 2127127A.AGK
