Problem N/A
History of Data The SEP classic data set used by Hale, Fowler, and Ottolini theses. The data tape was read and sorted by Jim Black in 1992. midpts.HH and shots.HH This rendition is windowed 8ms data. 250 midpts (rounds up to 256) is used in BEI in July 1995. allmidpts.HH This is the original 4ms data. 300 midpts (rounds up to 512).
