[Sane-analysis] Found source of data plotted on O'Connell's inclusive pions report

[O. A. Rondon]

After searching a little harder, I found the data plotted by hand in
O'Connell's report, Fig. 1
https://userweb.jlab.org/~rondon/oconnell-highp_inclusive-pions.pdf

The original paper is
"Production of Negative Pions from Hydrogen, Deuterium and Carbon by
High-Energy Electrons", F.H. Heimlich, G. Huber et al., Nucl.Phys. A267
(1976) 493

http://dx.doi.org/10.1016/0375-9474(76)90674-6

see fig. 5. I'm contacting Garth Huber about it, he may be one of the
authors.

Cheers,

Oscar
