Web9 Oct 2024 · Each line's integrated intensity is the sum of the intensities of its constituent Gaussians, and its wavelength is the weighted value of the same. We estimate the uncertainties on the reference wavelengths as the 1σ scatter in the wavelengths of the fits to the individual spectra from which the pre-flare averaged spectrum was derived. Web11 Apr 2024 · 1. The p.d.f. $f_Z$ of the sum of 2 normal random variables $Z=X+Y$ is computed by convolving $f_X$ with $f_Y$, or $f_Z (z)=\int_ {-\infty}^ {\infty}f_X (x)f_Y (z-x)dx$. It is not computed by taking the average of $f_X$ with $f_Y$. As Matías mentioned, … cow child
