Travel Time Structure (TRI grids)

Universal travel time structure, denoting travel times from specified points to specified stations for specified phases.

Field Type Units Description
layerid number - ID of the layer from which the nodes in NODEID are
nodeid numeric array - List of IDs of the nodes for which the travel times were computed traveltimes.nodeid(n) is the ID of the n-th node for which travel times were computed.
The corresponding phase name is traveltimes.phase(n,:) and the travel time itself is traveltimes.tt(n), in seconds.
phase string array - list of strings denoting the phases for which the travel times were computed
station string array - list of strings denoting the stations for which the travel times were computed
d numeric array deg list of the epicentral distances of the nodes
tt numeric array s list of the travel times themselve
