Dense Travel-Time Tables¶
The default travel time tables of SeisComP for LOCSAT [4] provide the
times in intervals of 1 degree epicentral distance. Thus, the curvature of the
travel-time curve at closer distance is not well imaged potentially resulting in
wrong locations or missing event solutions. Therefore, the LOCSAT tables,
iasp91_scanloc, based on the IASP91 model with higher spacial sampling are
added to the scanloc package. The table files are located in
$SEISCOMP_ROOT/share/locsat/tables
.
Note
gempa may provide additional travel-time tables as a service based on custom velocity models. Contact us for any related request.
Configuration¶
Configure association.table
and locator.profile
with
iasp91_scanloc for making use of the provided LOCSAT tables.
# Type of travel-time tables for phase association. May be different from locator.
# Use e.g. libtau or LOCSAT.
association.tableType = LOCSAT
# Name of travel-time table used for phase association. May be different from locator
# profile.
association.table = iasp91_scanloc
# The locator type to use
locator.type = LOCSAT
# The locator profile to use
locator.profile = iasp91_scanloc
