Overview
Cvmbycols is a set of codes for producing compacted Etrees for geographic regions with material properties drawn from a community velocity model.
Description
Defining properties of an Etree
The following properties are defined:
- Bounding box of geographic region in lon,lat coordinates
- Extents of Etree volume in 3D, in km
- Number of columns in x,y axis to partition 3D space. The resulting columns must be square along the x-y axis.
- Frequency limit to support in Hz
- Number of points per wavelength to support
- Minimum Vs to support
- Maximum octant size to allow
- Name of the output etree file
- CVM to use for material properties (from UCVM)
User Guide
Supported CVMs
The cvmbycols utility is built upon UCVM. As a result, it can extract etrees from the following CMV sources:
- CVM-H
- CVM-S
- USGS Cencal (which itself is an etree)
- 1D
