The sigma window value in dec tab

Hi Hiroshi,

I would like to know what is "sigma window value" and how to filter ms2 peak based on th sigma value? what's the meaning of
matchedFilterCoefficient in the souce code posted on the official website?
Code: [Select]
matchedFilterCoefficient[i] = (1 - Math.Pow((-halfPoint + i) / sigma, 2)) * Math.Exp(-0.5 * Math.Pow((-halfPoint + i) / sigma, 2))

Thanks in advance!

Best regards
yang
