DESCRIPTION                                                                   
     The programs prepfnd(1), fnd(1), steer(1),  fndlook(1),  and             
     powerfit(1)  either  read or write partially processed open-             
     loop radio science data in the fndo format. This format con-             
     sists  of  a  2048-byte header record followed by a variable             
     number of 2048-byte data records. Each data record  contains             
     128  double-precision complex data samples. The complex sam-             
     ples are each 16 bytes, with an 8-byte real part followed by             
     an  8-byte  imaginary part. All samples are considered to be             
     valid partially processed data. The record length may not be             
     set  by  the  user.  If  the  length  is  to be changed, the             
     aforementioned programs must be recompiled.                              
                                                                              
     All numerical quantities are stored in  native  SUN  format,             
     which  follows  the  ANSI/IEEE-754  standard and stores both             
     integers and floating  point  values  with  big-endian  byte             
     order.                                                                   
                                                                              
     The fndo header record includes the following structure plus             
     padding to 2048 bytes.
