Could you elaborate a bit more, and if possible make your comment an answer? Jul31 comment Optimal method to numerically integrate a spectral distribution data By least-squares you mean to fit the curve? Actually, there is not much of a theory behind this. This is the result of simulating the evolution of a collection of stars in a galaxy. This is not something like a Planck distribution for a black body. So I don't think fitting the curve would be advantageous at all. Jul31 comment Optimal method to numerically integrate a spectral distribution data @J. M. Actually this is not a real experimental data. This data is from a numerical simulation of a cluster of stars (which in turn uses real data with errors) As you said, the $\lambda$'s can be considered error-free. Jul31 comment Optimal method to numerically integrate a spectral distribution data @J. M. I've added a plot of $\log_{10}(\rho)$ vs $\lambda$. Unfortunately I don't know what the functional form of $\rho$ is.
