    Raw file information:
       There are 4 bits in each number to represent which channel that the
       number shall be in (Vax : bit 12-15, Sperry: bit 21-24).

       The 16 data channels are numbered from 0 to 15 : Blank, Volt. reference,
       Press. supp., Press. offset, Temp. supp., Temp. offset, Cond. supp.,
       Cond. offset, Bottle trip flag, Touch down flag, Press. supp., Press. offset,
       Temp. supp., Temp. offset, Cond. supp., and Cond. offset.

       Data file is formatted as 16I6.  Note that the number which appeaars in
       column 1 may not be channel 0 (because record may be out of sync.)

       Example : the address bit of number 7770 indicates it is channel 1,
                 hence it is Volt. reference. (7770= 0001 1110 0101 1010)
                 (on vax bit 12-15 of 7770 is 0001)
