You have highlighted the $64,000 question!

If you look at an actual graph, such as those at
http://hughes38.som.ohio-state.edu/spectra.htm (if they're still online,
I haven't checked recently), you'll see that the typical curve is jagged
and 'fuzzy', not a smooth rolling curve.

The question is: is the information that we really care about buried in
the nearly infinite amount of 'fuzz', and therefore not analyzable from
a practical point of view?

My statement is that if an experimenter --- perhaps a student doing a
doctoral thesis --- simplified the experiment as much as possible,
perhaps he or she could find out.

For whatever it's worth, if anyone tried the 'lead tape' approach,
probably it would be best to glue the lead tape and the tube together
--- in order that the instrument behaved as a single mass (rather than
the tube slipping back and forth inside the tape).

Cheers,
Bill
