I've posted to <http://www.stanford.edu/~siegman/Test_plot.pdf>
a
single-page PDF image (64 kB) which looks fine when opened in Adobe
Acrobat 7.0 or Safari on a Mac, but has severe problems (notably some
of the plot lines greatly thickened) when opened in Illustrator CS 11.
I'll be appreciative if anyone can dig into its innards and diagnose the
problem.
