ucvm_query

NAME
     ucvm_query

SYNOPSIS
     ucvm_query [-h] [-f config] [-m model] [-c coordtype] [-p map] [-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".

     -p       User-defined map of vs30 and elevation data.

     -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.

basin_query

NAME
     basin_query

SYNOPSIS
     basin_query [-h] [-f config-file] [-m model] [-v vs-threshold] [-p usermap] [-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.

     Less Used Parameters

     -p       Custom vs30 and elevation map location.

     -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
