# The stations to process.
# Path to a stations file in hypoinverse (.hinv) format.
# File format description:
# http://www.earthwormcentral.org/documentation2/USER_GUIDE/hypoinv_sta.html
# Keep in mind, that the file is a fixed length format and NOT space-delimited.
StationFile ${EW_PARAMS}/thresh_subtrig/stations.hinv
# The minimum search radius [m].
# Stations with distances smaller than MinSearchRadius will be ignored.
MinSearchRadius 1000.0
# The maximum search radius [m].
# Stations with distances larger than MaxSearchRadius will be ignored.
MaxSearchRadius 15000.0
# The maximum number of sub-stations.
# A subnet will contain at most the MaxNSubStations nearest stations.
MaxNSubStations 10
# The subnet trigger threshold.
# The number of sub-stations with threshold crossings needed to trigger
# the subnet.
TriggerThreshold 5
# The velocity used to compute subnet time windows [m/s].
# The subnet listening time is computed using the maximum sub-station
# distance divided by VMin.
# trigger_time_window = max_station_distance / v_min.
VMin 3500.0
# The factor used to compute the idle_listen_time.
# idle_listen_time = idle_listen_time_factor * trigger_time_window.
IdleListenTimeFactor 3.0
# The maximum allowed latency of threshold alerts [s].
# Threshold crossings with a larger latency are not processed.
MaxThreshCrossLatency 40.0
