The TTCURVES structure is used to store an entire set of travel time curves.
The ttc substructure is an array which contains data for the i-th phase in ttc(i). The name of the i-th phase is ttc(i).p, the travel time of the j-th ray of the i-th phase is given in ttc(i).t(j).
Field | Type | Units | Description |
---|---|---|---|
name | string | - | model name (usually taken from the name field of a model structure) |
dangle | numeric scalar or numeric vector |
° | delta takeoff angle. scalar: the MKTTCURVES routine shoots rays into every direction between 0° and 90°, in steps of DANGLE. vector: explicit list of takeoff angles |
h | numeric scalar | km | focal depth for which travel time curves are computed |
anz | numeric | dimensionless | number of phases contained in ttc substructure |
ttc | struture array | - | substructure containing the actual travel time curve data |
Field | Type | Units | Description |
---|---|---|---|
p | string | - | name of phase |
d | numeric array | ° | Epicentral distances at which travel times are given |
rayp | numeric array | °/sec | Ray Parameters from which travel times are computed |
angle | numeric array | ° | Take Off angles from which travel times are computed |
t | numeric array | s | t(n) is travel time of phase p at distance d(n) |
