Refraction diagram

[S.V.V.ARUN KUMAR]

Dear all,

I need a computer software (or atleast FORTRAN program) to construct Wave rays (Refraction diagram). Can anybody send me a link for getting this software.

Urgent please

Kind regards,

[rouf]

I have density profile as well as vertical distribution of current data with time for a fixed station. How can I calculate and draw wave rays with these data.
Can anyone give me some hints?
with regards
