NAME
ucvm_query
SYNOPSIS
ucvm_query [-h] [-f config] [-m model] [-c coordtype] [-v] [-z zmin,zmax]
DESCRIPTION
The command ucvm_query queries an installed velocity model to retreive its material properties
at a particular latitude and longitude.
Any set of crustal and GTL velocity models may be selected and queried in order of preference.
Points may be queried by (lon,lat,dep) or (lon,lat,elev) and the coordinate conversions for
a particular model are handled transparently.
Common Paramters
-h Displays the help message.
-f Location of the configuration file, config, that tells the program which velocity models are installed.
-m A comma-separated list of models to query.
Less Used Parameters
-c Z-coordinate mode. Geo-depth (default) is "gd",
but queries can also be done by elevation as specified by "ge".
-v Display model version information only.
-z Specifies depth range for gtl/crust interpolation.
EXAMPLE
ucvm_query -f ../conf/ucvm.conf -m cvms
Input format is:
lon lat Z
Output format is:
lon lat Z surf vs30 crustal cr_vp cr_vs cr_rho gtl gtl_vp gtl_vs gtl_rho cmb_algo cmb_vp cmb_vs cmb_rho
If running in interactive mode, please use Ctrl-D to end the input.

NAME
basin_query
SYNOPSIS
basin_query [-h] [-f config-file] [-m model] [-v vs-threshold]
[-z zmin,zmax] [-d max-depth] [-i interval] < file.in
DESCRIPTION
The command basin_query allows you to retrieve the depth at which vs-threshold is first crossed.
By default, vs-threshold is set to be 1000m/s, but that can easily be changed.
Common Paramters
-f Location of the UCVM configuration file. Typically, this is ../conf/ucvm.conf.
-m Model to query. Usually model is either cvms, cvmh, cvmsi, or cencal.
-v Vs threshold to use. By default this is 1000m/s, but other common values include 2500m/s and 3000m/s.
-z Custom depth range for GTL/crust interpolation.
-d Maximum depth, in meters, to search. Default is 15000m.
-i Interval, in meters, go go by when searching for the depth. Default is 20m.
So basin_query will get the Vs value at 0m, 20m, 40m, and so on.
EXAMPLE
basin_query -f ../conf/ucvm.conf -m cvms -v 2500
Input: -118 34 Ctrl-D
Output: -118.0000 34.0000 4780.000 4780.000

NAME
ucvm2mesh
SYNOPSIS
ucvm2mesh [-h] -f config
DESCRIPTION
The command ucvm2mesh generates a mesh in either IJK-12, IJK-20, IJK-32, or SORD format.
It does so by reading in the specifications in a given configuration file, config.
This mesh can then be used in forward 3D wave propagation simulation software such as AWP-ODC.
-h Displays the help message.
-f Uses configuration file, config.
EXAMPLE
ucvm2mesh -f ./ucvm2mesh_example.conf

# List of CVMs to query
ucvmlist=cvmh

NAME
ucvm2mesh-mpi
SYNOPSIS
ucvm2mesh-mpi [-h] -f config
DESCRIPTION
Notice: ucvm2mesh-mpi is meant to be run as a MPI job, not as a standalone executable.
The command ucvm2mesh-mpi generates a mesh in either IJK-12, IJK-20, IJK-32, or SORD format.
Unlike its serial version, ucvm2mesh this command can use multiple cores to generate the mesh.
It does so by reading in the specifications in a given configuration file, config.
This mesh can then be used in forward 3D wave propagation simulation software such as AWP-ODC.
-h Displays the help message.
-f Uses configuration file, config.
EXAMPLE
mpirun -np [procs] ucvm2mesh-mpi -f ./ucvm2mesh_example.conf
Where ucvm2mesh_example.conf is:
# List of CVMs to query

NAME
ucvm2etree
SYNOPSIS
ucvm2etree [-h] -f config
DESCRIPTION
The command ucvm2etree builds an e-tree from the specifications in a given configuration file, config.
Note that this is the serial version of the command, meaning that it will only run on a single process. As such, building a
large e-tree can be very slow. For large e-trees, we strongly recommend using ucvm2etree-extract-MPI, ucvm2etree-sort-MPI, and
ucvm2etree-merge-MPI.
-h Displays the help message.
-f Uses configuration file, config.
EXAMPLE
ucvm2etree -f ./ucvm2etree_example.conf
