These Iota Herculis UV spectral atlas data are on a binary magnetic tape created on an IBM 360 computer. The tape contains three files. File one is the second-order spectrum; file two is the first-order spectrum; and file three contains a program to read and list files one and two. The spectral data are blocked at ten 145-word logical records per physical block. The first word of each logical record contains the number of sets of data (24, except for the last set) in each read. It is followed by words containing wavelength in angstroms of a data point; corrected count rate for the wavelength point (scattered light has not been removed); smoothed count rate computed at the wavelength point using a Fourier smoother; scattered light estimate derived by experimenter; normalized smooth count rates as displayed in the atlas, with unity at the top of each plot; and scattered light normalized using the same normalization factors as were used on smoothed count rates. These data are detailed in W.L. Upson II and J.B. Rogerson, Jr., "The Copernicus Ultraviolet Atlas of Iota Herculis," Astrophys. J. Suppl., v. 42, p. 1, 1980.
