ICE Plasma Wave Archive Data Format


E-channel data file
Header - two lines:
      Year and Julian day number  (Jan. 1 = Day 1)
      File starting time (in milliseconds from the start of the day and in 
hh:mm:ss.ss) and file ending time (in the same format)


Subheader - one line (flagged by a "-99" at the beginning of the line):
      Bit rate (values: 1 = 1 second data samples, 2 = 0.5 second, 3 = 2 
second, 4 = 8 second) and antenna modes (values: 1 = u, 2 = v, 0 = bad) 
separated by commas. Note that subheaders may not always be followed by data. 
If there was bad header data, the frame was zeroed out.


Data - Time in milliseconds, calibrated 16 channel data (in order of lowest 
to highest frequency. Values: 17.8, 31.6, 56.2, 100, 178, 316, 562, 1000, 
1780, 3160, 5620, 10000, 17800, 31600, 56200, 100000 Hz) in units of 
volts/(meter-Hz**1/2)


B - channel data file
Header - two lines:
      Year and Julian day number  (Jan. 1 = Day 1)
      File starting and ending time (in same format as E-channel)


Subheader - one line (flagged by a "-99" at the beginning of the line):
      Four calibration flags (ignore, only used for processing the data into 
archive format), bit rate (same as for E), antenna modes (same as for E)


Data - Time in milliseconds, calibrated 8 channel data (in order of lowest to 
highest frequency. Values: 17.8, 31.6, 56.2, 100, 178, 316, 562, 1000 Hz). 
Notice that the lines are padded with zeroes. We only get one B sample at a 
time. Units: nT/(Hz**1/2) 


------------
File names have the following format:

      PEyymmddhh.#   or   PByymmddhh.#

where:
      P:  signifies processed data
      E or B:  signifies E-field or B-field data respectively
      yy:  indicates the year (85 for 1985)
      mm:  indicates the month number (09 for September)
      dd:  indicates the day of month
      hh:  indicates the starting hour of data in file
      # :  indicates the file number in sequence


Example:  PB85091017.19 is file containing magnetic field data for (part or 
all of) hour 17 on 1985-Sep-10.

(Note: a given file may contain data for more than one hour; alternately, 
data for a given hour may be distributed in more than one file; precise 
timing information is contained in the data records within the files).
