The eight files are divided into 4 pairs of files with each pair consisting of a file containing data averaged over a 10 minute period and a file containing the maximum data value during the same 10 minute period. The 4 pairs of file contain data for the RAR, the PFR, WFA - magnetic field, and WFA - magnetic field. A.3 Waveform Analyzer Electric Field Four UDS files are produced per day for the WFA data. Two of the files contain average and peak data for the Ex signals and two files contain average and peak data for magnetic field data. The high band channels (upper 12 frequencies) always contain By. The low band channels (lower 10 frequencies) contain either By or Bz depending on the mode of the instrument. A flag specifying the mode is provided for each time interval. The lowest two frequencies of the WFA are derived in a different manner so they have been left out of the UDS data. This leaves 10 frequencies from the low band and 12 frequencies from the high band. The frequencies are given below. The peak data provided by the WFA high band frequently do not exceed the threshold background so the average values have been used in all cases. The files of 10 minute averaged data were computed by, for all data falling within the 10 minute periods, finding the average values for each frequency. Similiarly, the files of peak data were computed by, for all data falling within the 10 minute periods, finding the maximum value for each frequency. The WFA data is affected by interference from other instruments. In particular, interference from the PFR occurs and is dependent on the PFR scan mode. For this reason a flag indicating the PFR mode is provided in the WFA files. WFA electric field data: The names of the files are (following the PDS convention): Tyyddd.TAB -> Average data Tyyddd.TAB -> Peak data yy: Last two digits of year. ddd: Day of year (1..366). The files are Ascii and contain one line for each time period (even if there are no valid data for a time period) so they contain 144 lines each. The format of the data is indicated by the following Fortran read statement (which can be used to read the files): DIMENSION F(22) READ(1,100) TIME,IPFRMODE,IBPS,F 100 FORMAT(A24,1X,A3,A1,22(1X,1PE92)) The variables are defined as follows: TIME: Spacecraft event time in the format yyyy-mm-ddThh:mm:ss.sssZ. PFRMODE: Indicates the scan mode of the PFR instrument. 1: Fast scan mode. 2: Slow scan mode. 3: Fixed-frequency mode. 4: The mode switched during the averaging interval. 5: The mode could not be determined. BPS: Telemetry bit rate: 1: 128 bps. 2: 256 bps. 3: 512 bps. 4: 1024 bps. 5: Bit rate changed during averaging period. 6: Bit rate unknown. F: Contains the data for Ex (either average or peak values, depending on the file) of the 22 frequency channels. The frequencies are: F(1): 0.22 Hz F(2): 0.33 Hz F(3): 0.44 Hz F(4): 0.66 Hz F(5): 0.88 Hz F(6): 1.33 Hz F(7): 1.77 Hz F(8): 2.66 Hz F(9): 3.55 Hz F(10): 5.33 Hz F(11): 9.00 Hz F(12): 14.00 Hz F(13): 19.00 Hz F(14): 28.00 Hz F(15): 37.00 Hz F(16): 56.00 Hz F(17): 75.00 Hz F(18): 112.00 Hz F(19): 149.00 Hz F(20): 224.00 Hz F(21): 299.00 Hz F(22): 448.00 Hz These data are electric field intensities detected by the Waveform Analyzer (WFA) on the X antenna of the URAP instrument. Units: microvolt/Hz**.5 measured at the receiver input terminals. To convert to electric field strength the given data must be divided by the effective length of the antenna. This is complicated by the fact that the effective length depends on the antenna impedance which is affected by the plasma conditions local to the Ulysses spacecraft. The impedance will also depend on the frequency. In general, the WFA frequencies can be affected by the plasma so a single number cannot be used for the effective antenna length.
