hello list,

I see VASP files now. Do you use it, and for what it is useful ?

I see the word "hanning" in some patchs to make fonction in table. I think it's like a sinus. For what is it useful too?

Usually the 'hanning' window is used to envelope a block of samples before passing them to an FFT routine so the discontinuities at the two ends don't show up as spurious high-frequencies.
