Open Loop Data ============== Data Collection --------------- No new data. Analyses -------- Joe Twicken has added data from the 97/299 periapsis pass to his LGT1 pattern collection. The new antenna pattern is included here as Figure HEA7304A.PS1; it replaces HEA7302A.PS1. Closed Loop Data ================ Data Collection --------------- We have obtained the following files from OSCAR and EPIC: Original File Name Name on SOPC ------------------------------ ------------ ATDF: 97298T299.DAT;1 7298299A.TDF 97299T301.DAT;1 7299301A.TDF 97300T302.DAT;1 7300302A.TDF ODF: 97303O303.DAT;1 7303303C.ODF 97303O2314.DAT;1 7303303B.ODF 97303O304.DAT;1 7303304A.ODF 97304O1600.DAT;1 7304304A.ODF IONCAL: TROPCAL: WEATHER: EOP: Anomalies --------- Transfer of the 3 ATDFs was initiated yesterday afternoon; they came in very slowly until after about 06h UT, when the last file was transferred in about 20 minutes. Ancillary Data ============== Data Collection --------------- We have obtained the following files from the CDB and other sources: Original File Name Name on SOPC ------------------------------ ------------ LIT: ltm_i_971029-971031_top_short 7302304A.LIT OPT: optg_i_971106-971123_Reset09 7300015A.OPT OPT: optg_i_971029_OD031_041_V1 7302319A.OPT SAK: mgs_solar_array_1997-302.ck 7302302A.SAK SAK: mgs_solar_array_1997-303.ck 7303303A.SAK SFO: p031c.03.sfos 7302310F.SFO SFO: p031c.04.sfos 7302310G.SFO SOE: p031c.03.soe 7302309F.SOE SOE: p031c.04.soe 7302309G.SOE SPK: spk_i_971106-971123_Reset09 7300015A.SPK SPK: spk_i_971029_OD031_041_V1 7302319A.SPK TCK: mgs_spice_c_kernel_1997-302.ck 7302302A.TCK TCK: mgs_spice_c_kernel_1997-303.ck 7303303A.TCK Figure Captions =============== HEA7304A.PS1: LGT1 normalized antenna pattern for three dates on periapsis passes. Plot symbols distinguish pre-periapsis data from post- periapsis data. The higher pre-periapsis values over the range 5-30 deg suggest the pattern is not axially symmetric, consistent with the data plotted in Figure 3-7 of the MGS TCS Operations Reference Handbook (JPL D-14027). This figure replaces HEA7302A.PS1. Figures ======= Plot(s) illustrate some of the points made in the text. Each plot is a PostScript file, created and printable on our SOPC. For report text file HEAydddC.TXT Figure N will be labeled HEAydddC.PSN and sent as the N+1st e-mail message of a set. We assume that you can strip off the e-mail headers and either display or print copies of the figures on a machine in your area. People who have indicated that they cannot handle these files by e-mail are not included in the e-mail distribution of figures.
