Gaussian peak fitting

WebHowever, in IDL, the Gaussian distribution fitted by GAUSSFIT is described by: where. where A 0 = Peak intensity. A 1 = Peak position. A 2 = width of Gaussian. Importantly, this width is not the FWHM, but is in fact s - the factor is lost - so in order to calculate the total emission from the line, it is important to convert this width to the FWHM.
