Hi -
the maximal difference in this case is of about 6 (units?), which is an
approximately 50% difference. This is in one point in the spectrum which has
a relatively small value - the maximal peaks in the spectra are on the order
of 1200, so in the grand scheme of things, not that horrible. Other large
differences are on the order of 4, which is approximately 5% or less of
those points.
Thanks - Ariel
PS for some reason, matplotlib-devel will not get your email unless you hit
"reply all", so they have been getting my emails, but not yours. I am not
sure whether that is what you intended, so I thought I would mention it.
