gpiv_s-avg - Spatial statistics of PIV data.
gpiv_s-avg [-h | --help] [-p | --print] [-s] [-no_s] [-v | --version]
[filename] < stdin > stdout
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
-h | --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
-no_s Suppresses subtracting the mean values from the input data.
-v | --version
Prints version information on standard output, then exits
[-z dx0 dy0]
zero offset of displacement or velocity estimators.
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

The program has been tested for PIV data. So far, no bugs have been
