These files are the reports given by Dr Junwei, Zhao and Deanyi, Zhou in the 2010 Summer School which was sponsored by professor Shaolan, Bi in Beijing Normal University. Some IDL or Fortran codes in Junwei's directory can be used to draw k-oumiga, time-distance, and ring diagrams. These programs are developed for students who want to know the helioseismology. Please pay attention to the copyrights if you use them for other purposes. That means you must notify Dr Junwei, Zhao before you use (or modify) his codes in your 'scientific' study or any publications.
