gaussian convolution [message #53176]

Hi there,

I have a (theoretically computed) spectrum and I would like to degrade
it to a lower resolution.

I was wondering if there is any standard procedure to do it and/or
some "pre-cooked" routine in IDL. Is there any gaussian filter
routine?

My first guess would be to use a gaussian filter in order to reduce
the resolution. The spectrum is (intensity vs. wavelength),so I
think 1D gaussian filter would be OK. Is there anyone with experience
on it ?

Suggestions are welcome, thanks! Cheers,
Tim
