19 \fBgpiv_s-avg\fP reports the spatial global mean velocities and
20 variances in x and y-direction of a PIV data stream. Only input data
21 of which the peak number is not equal to -1 are taken into
24 The parameters read from the configuration resources (containing the
25 key \fBPOST\fR) may be overruled by the command line options, as
31 \fB-h\fR | \fB--help\fP
35 \fB-p\fR | \fB--print\fP
36 Prints parameters, command line options and input and eventually filenames
37 to stdout. The output is identic of \fIfilename\fB.par\fR, in case
41 Subtracts the mean x-and y-particle displacements from the input data.
45 Suppresses subtracting the mean values from the input data.
48 \fB-v\fR | \fB--version\fP
49 Prints version information on standard output, then exits successfully.
53 zero offset of displacement or velocity estimators.
57 Input PIV file. Overrides stdin and stdout. The output will be
58 written to \fIfilename\fB.sa.piv\fR. Parameters are stored in
59 \fIfilename\fB.par\fR and may be used for future use by including them
73 The program has been tested for PIV data. So far, no bugs have been
