具有特色的地震数据处理源码

%This script can be used to run qc_dsi with
%many input vsp data files. This script isolate 
%all 15 traces from each depth position of the survey and 
%outputs H1 azimuth into header 11 of all data files. 
%You still need to rotate the data after using this script.

%loading each individual VSP profil files and taking subsets
%corresponding to the first breaks time interval
