Is this FWHM in centimeter unit or in millimeter unit? Thanks a lot.

Hi Hae-Jeong,
it is:
fwhm = (2.3*sqrt(niter*2/pi));
cheers, Bruce

Hi,
I would like to know the relationship between number of iteration in

smoothing and Gaussian kernel size in FWHM.
Would you give me some information on this? Thank you in advance.
