Seasonal Variation in Trend Analysis [message #56078]

Folks,

Does anyone happen to have an IDL example of some
code that might remove seasonal variation in a time
series? Or some suggestions for how to proceed in IDL?
I can see that I might want to use a model that has
sin and cosine terms, but I can't see how to find the
coefficients of such a model in IDL.

Cheers,

David
