New page
Usage: gpsh [OPTIONS] [FILE]
Compute SH transfer function for layered models given through stdin or FILE.

Format for layered models:
Line 1 : <number of layers including half-space for first model>
Line 2 : <thickness (m)> <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)> <Qp> <Qs>
....
Line n : 0 <Vp (m/s)> <Vs (m/s)> <Density (kg/m3)> <Qp> <Qs>
Line n+1: <number of layers including half-space for second model>
....

Quality factors are mandatory. Any number of models can be given as input.

Gpsh options:
-n <count> Number of samples (default=100)
-max <max> Maximum of range for transfer function (default=20)
-angle <angle> Incidence angle (default=90, vertical incidence)

Generic options:
-help <SECTION> Show help about options. SECTION may be empty or:
all, examples, generic, gpsh
-version Show version information
-app-version Show short version information
-reportbug Start bug report dialog, information about bug is
passed through stdin. This option is used
internally to report bugs if option -nobugreport is
not specified.
-reportint Start bug report dialog, information about
interruption is passed through stdin. This option
is used internally to report interruptions if
option -nobugreport is not specified.
-nobugreport Do not generate bug report in case of error

Examples:

gpsh < test.model

Calculate SH transfer function from 0.2 Hz to 20 Hz for model 'test.model'.

gpsh < test.model | figue -c

Calculate the same function and plot it.

gpsh < test.model | figue -c -m sh.mkup

Show the same function on a log-log plot. 'sh.mkup' is a tar.gz file
containing an xml description of the graphic format, it can be generated from
figue's interface.
