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  file-
	      name.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.

       gpivtools

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.

NAME

       gpiv_s-avg - Spatial statistics of PIV data.

SYNOPSIS

       gpiv_s-avg [-h | --help] [-p | --print] [-s] [-no_s] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       gpiv_s-avg reports the spatial global mean velocities and variances in x and y-direction of a PIV data stream. Only input data of which the
       peak number is not equal to -1 are taken into account.

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

Options
       -h | --help
	      On-line help.

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

       -s     Subtracts the mean x-and y-particle displacements from the input data.

       -no_s  Suppresses subtracting the mean values from the input data.

       -v | --version
	      Prints version information on standard output, then exits successfully.

       [-z dx0 dy0]
	      zero offset of displacement or velocity estimators.

       filename
	      Input PIV file. Overrides stdin and stdout. The output will be written to filename.sa.piv. Parameters are stored in filename.par and
	      may be used for future use by including them in ./gpivrc.
