Documentation for program Dynap (Version 2.0) may be found
in the file called documentation.

DYNAP requires that its input files to be named AFILE, BBOOK 
and (if there is GPS data) GFILE.  The AFILE, GFILE, and BBOOK
files given here are example input files for DYNAP.
The dynap.out file is the output file containing the
results of the DYNAP program using the data in the AFILE,
GFILE, and BBOOK files.

The files ending in ".f" are FORTRAN-77 code.  These files must
be compiled together.

The number of stations/observations that can be used with DYNAP
varies with the size of the arrays.  Most of the arrays are
sized to hold up to 9999 stations.  The main data array (A, defined
in line 80 by the parameter LENA) is the most important for
controlling the size.  If LENA is set too large, then the
program may not compile.  But even if it does compile, the computer
may not be able to execute it.  On the other hand, if it is set
too small, then it is may not be big enough for the number
of stations in a given set of observations.
