homogeneous¶
Travel-times for a homogeneous velocity model
Description¶
The travel-time interface homogeneous allows predicting travel times for P and S wave and homogeneous velocity models.
Configuration¶
The travel-time interface homogeneous is controlled by global parameters,
e.g., in $SEISCOMP_ROOT/etc/global.cfg:
Add a new table profile for homogeneous travel-time tables with some custom profile name. In scconfig navigate to the section ttt.homogeneous and click on the green button to add a table profile.
Set all parameters in the new profile.
Register the new profile by adding its name to the list of tables in
ttt.homogeneous.tables
Example configuration for P, S (seismic) and Is (infrasound):
# The list of supported model names per interface
ttt.homogeneous.tables = "5"
# Geographic origin of the region. Expects 2 values: latitude, longitude.
ttt.homogeneous.5.origin = 51, 12
# Maximum radius around origin
ttt.homogeneous.5.radius = 1
# Minimum source depth
ttt.homogeneous.5.minDepth = 0
# Maximum source depth
ttt.homogeneous.5.maxDepth = 2
# Phases and velocities
ttt.homogeneous.5.velocities = P:5,S:3,Is:0.3
Application¶
Once the travel-time interface profile is defined and registered, in can be selected
Interactively in the scolv phase picker or the scolv amplitude picker,
Or used in other modules which allow the configuration of travel-time interfaces or locators such as FixedHypocenter or StdLoc.
