The Chromospheric Spectrum at the 1962 Eclipse
Abstract
A joint expedition of the High Altitude Observatory, Sacramento Peak Observatory, and the National Bureau of Standards obtained slitless spectrograms of the flash spectrum at the February 5,1962, total eclipse of the Sun. The spectrograms covered the wavelength range of about 3200 to 9100 A with a height resolution of 100 km. The spectrographic equipment, the observations, the photometric calibration procedures, and the methods adopted to reduce the large quantity of data are described. The results are presented in a set of tables that show the wavelength and identification (where known) of each of the 3500 lines recorded. A separate set of tables lists the intensity of each line at each height. The latter tables are ordered according to the element, ionization stage, and multiplet number associated with the line.
