Just keep in mind that spectra are one of the cases where typically
what would be of interest when downsampling is not to have points that
"fall on the original line", as show in David's plot. It may be points
that preserve the same area under the curve. Like the difference
between a downsampled curve and one convolved with a kernel (which
brings the additional question of which kernel to use).
