/* General overview of the data record format */

   Each record covers ten milliseconds of data.  Each record
consists of an 8 byte header and a variable number of 8 bit
data values.  The header items have the most significant byte
first and can be declared on the MAC and the SUN as "int short'
in C and real*2 in fortran.  On machines like the VAX the 2 
byte value must have the order of the bytes swapped.  The data
values are unsigned bytes ranging from 0 to 255 with 127.5 the
0 point value.  These values are units representing the values
of the digitized wave form. 

   * The Header:  four unsigned short values (8 bytes total)
      - the record size in bytes (not including these two bytes)
      - the time offset from the start of the minute in milliseconds
      - some sort of flag 
      - the number of 8 bit data samples in this record
      

   In order to get the actual time of the data, you have to
deconstruct the filename.  The format of the filename is:

                dddhhmm.yyw

where yy is the year, ddd is the day of year, hh is the hour,
and mm is the minute. 'w' stands for 'wideband' or 'L' for 'label'.
