TTCURVES structure

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).

ttcurve structure
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

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)
