Good and Bad Depth Sampling

Used Velocity Models

The examples given in this section are all computed with routines and models contained in the TTBOX distribution, enabling the reader to repeat and extend them.

All examples use a number of example models that were generated using the following commands:

%%% read the IASP91 model in its polynomial form
iasp91=mkreadclr([mkttboxdata 'iasp91.clr'],'silent');

%%% depth sample distance: 1km in flat earth coordinates
%%% This is a very good sampling and serves as reference in the following
iasp91_1km=mkclr2model(iasp91,1,'flat');


%%% depth sample distance: 10km in flat earth coordinates
iasp91_10km=mkclr2model(iasp91,10,'flat');
%%% depth sample distance: 50km in flat earth coordinates
iasp91_50km=mkclr2model(iasp91,50,'flat');

%%% depth sample distance: 100km in flat earth coordinates
iasp91_100km=mkclr2model(iasp91,100,'flat');


%%% depth sample distance: 100km in spherical coordinates
%%% For core phases, this is a really bad depth sampling
iasp91_100km_sph=mkclr2model(iasp91,100,'spherical');

%%% depth sample distance: 10km in spherical coordinates
iasp91_10km_sph=mkclr2model(iasp91,10,'spherical');
