Collection Overview
===================
A UDS data files
Eight files are provided that conform to the UDS conventions
regarding the naming of files and the format of the data. 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.4 Waveform Analyzer Magnetic Field
The names of the files are (following the PDS convention):
Tyyddd.TAB -❯ Averaged 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,IANTENNA,IBPS,F
100 FORMAT(A24,1X,A2,A1,A1,22(1X,1PE9.2))
The variables are defined as follows
TIME : Spacecraft event time in the format
yyyy-mm-ddThh:mm:ss.sssZ.
ANTENNA: Antenna used for low band (0.22 to 5.33 Hz). The
high band (9.8 Hz and above) is always By.
1: By
2: Bz
3: Antenna switched during the averaging interval.
4: Antenna unknown.
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 By or Bz (peak values) 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 magnetic field intensities detected by the
Waveform Analyzer (WFA) on the URAP instrument.
Units: 10**-15 Tesla/Hz**0.5
Time resolution: 10 minutes
Fill value for bad or missing data is -9.99e+10.
