Rayleigh Wave Dispersion (programs gendis and disper)

The program disper computes Rayleigh wave dispersion curves which can then be input to program waves for synthetic seismogram computation. The computation is taken directly from Aki and Richards (1) (chapter 7 on surface waves). Because there are a large number of input variables, the program disper uses a file with namelists. Since velocity and density are easier values to input than elastic moduli, a helper program is also available, gendis. Man pages exist for both disper and gendis. From an x-term, type

man gendis

or

man disper.

There is no online help as with other BSU programs. That is DO NOT TYPE:

disper -h

All this will do is create an empty file named -h, and that will be difficult to remove unless you know how to do it (the problem is the dash). If you have already made this mistake, you can remove the empty file as follows:

rm ./-h
