NAME

       gpiv_vhisto  - Tests PIV data by printing/displaying an histogram of the vertical particle
       displacements.

SYNOPSIS

       gpiv_vhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin >
       stdout

DESCRIPTION

       Gpiv_vhisto  calculates  the  histogram of the vertical particle displacement distribution
       between minimum and maximum values.

       The parameters read from the configuration resources (containing the  key  VALID)  may  be
       overruled by the command line options, as explained below.

Options

       -g     Graphical visualization of the histogram with gnuplot.

       -h | --help
              On-line help

       -n N   Override number of bins (default 10, hard coded).

       -p | --print
              Print  parameters,  command  line  options  and  eventually  used  input and output
              filenames to stdout.  The output is identic of filename.par, in case -f is used.

       -v | --version
              Print version information on standard output, then exit successfully.

       filename
              Input PIV file. Overrides stdin and stdout. Output will be written to filename.pdf.
              The  parameters  will  be  written  or appended to filename.par and may be used for
              future use by including them in ./gpivrc.

NOTES

       stdin and stdout has still to be implemented.  [-f filename ] will be added.

BUGS

       The program seems to work fine with real PIV data.  So far,  no  serious  bugs  have  been
       found.
