Watson, retired, concerning the data.  It was Mr. Watson’s visit to NIST in the late 1980s to discuss the hot-plate data that later inspired this endeavor.  The author appreciates the valuable contributions on data presentation made by Peter Linstrom and the many discussions with Dr. Charles P. Sturrock, Dorothy M. Blakeslee, and Dr. A. Hunter Fanney.  The author appreciates the efforts of the following individuals who assisted with the data preparation over several years: Teresa A. Wright, Kevin E. Simmons, Kenneth P. Kramp, Jareb D. Ketay-Paprocki, and Susan M. Fioravante.
