000001859 520__ $$aThe authors present a catalogue of over one hundred digitised photographic images of Comet Halley obtained during the 1985 - 1986 apparition. The data were taken using telescopes at Xinglong Station of Beijing Observatory, China, and at Mt. John Observatory, New Zealand. Many activities of the plasma tail, such as jets, kinks, helices, rays, condensations and disconnections were recorded. All photographic images have been digitised using the PDS 2020GM microdensitometer at the Astronomical Institute of the University of Muenster, Germany. The authors present the catalogue of density and intensity images, and give the transformation formulae for calculating the relative intensities. A similar number of standard-star density frames are included, as well as about 400 spot-sensitometer calibration frames.
