The Savitsky-Golay filter is discussed in Num.Rec. (2nd Edit.) pg. 652. I am considering trying to write it in IDL, but am wondering if anyone might already have done this. Any pointers would be appreciated. Sincerely, Russ Welti rwelti@u.washington.edu
Re: Seeking Savitsky-Golay (savgol) filter.
You can find a procedure to apply a Savitzky-Golay filter in the Astronomy User's Library. It is called POLY_SMOOTH and can be found in the Math directory. Regards, Michele Scutter
