Problems in printing/viewing?

• The files above are available in PDF and postscript.
• Some figures may not display well on some monitors, but have printed satisfactorily in our testing.
• Occasionally the Greek letters (sigma, lambda, pi) embedded in the document generate errors or are translated into Roman letters (s, l, p). This is apparently a function of the specific fonts installed on any given system. We have not successfully found a remedy for this problem, but it occurred only about 10% of the time in our testing.
• Sorry, we do not have printed copies available at this time.
