@Robert Thanks! Could you elaborate a bit more, and if possible make your comment an answer?

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.

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.

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.

comment I need mathematical proof that the distance from zero to 1 is the equal to the distance from 1 to 2
Some deep and philosophical questions about the foundations of mathematics is discussed in Mari Livio's new book "Is God a Mathematician"
