CHRISTOPHER RUSSELL, DR. FREDERICK SCARF, DR. ROBERT STRANGEWAY, MURIEL KNIFFIN Collection Overview ==================== This data collection, PVO OMAG/OEFD Phase and Offset ASCII Data Collection (urn:nasa:pds:pvo-omag-oefd-anc:data-phaseoff-asc), contains data which maybe used to assess the quality of the OMAG and OEFD science data. The data contains the phase amplitude of sun synchronous modulation of the 4 signals (E100, E730, E5.4 and E30K), and offsets of the G sensor. They contain the following information: RECORD LENGTH = 133 NUMBER OF COLUMNS = 13 OPERATING SYSTEM = SUN/UNIX # NAME UNITS SOURCE DESCRIPTION 001 UT PVO Universal Time given in PDS format: yyyy-mm-ddThh:mm:ss.sss 002 E100_PH deg PVO EFD Phase of sun synchronous modulation of E100 signal. 003 E100_AMP V/m/Hz**.5 PVO EFD Amplitude of sun synchronous modulation of E100 signal 004 E730_PH deg PVO EFD Phase of sun synchronous modulation of E730 signal 005 E730_AMP V/m/Hz**.5 PVO EFD Amplitude of sun synchronous modulation of E730 signal 006 E5.4KPH deg PVO EFD Phase of sun synchronous modulation of E5.4 signal 007 E5.4KAMP V/m/Hz**.5 PVO EFD Amplitude of sun synchronous modulation of E5.4 signal. 008 E30K_PH deg PVO EFD Phase of sun synchronous modulation of E30 signal 009 E30K_AMP V/m/Hz**.5 PVO EFD Amplitude of sun synchronous modulation of E30 signal. 010 TAV nT PVO MAG Offset subtracted from T sensor in data processing to get a sine wave centered on zero. 011 GDIFFX nT PVO MAG Correction of the G sensor data for the spacecraft field along the X direction 012 GDIFFY nT PVO MAG Correction of the G sensor data for the spacecraft field along the Y direction. 013 GDIFFZ nT PVO MAG Correction of the G sensor data for the spacecraft field along the Z direction. MISSING DATA FLAG = 999.999 AVERAGE INTERVAL = 00:00:24.000 A binary version of these data is available in the PVO OMAG/OEFD Phase and Offset Binary Data Collection (urn:nasa:pds:pvo-omag-oefd-anc:data-phaseoff-bin) Confidence Level Overview ========================= These data have been reprocessed several times during the course of the mission. Each successive reprocessing has eliminated some of the problems found in earlier version of the data. Please bring to the attention of the original investigator any suspicious section of data. No zero level correction has been applied to the data because of the small size of the determined zero level. References ========== Russell, C.T., R.C. Snare, J.D. Means, and R.C.
