***** File AAREADME.TXT This dataset contains data obtained through the efforts of the International Halley Watch (IHW) Disciplines and the Lead Center. From the original compact disk (one of a 2-disk set), several datasets have been created, one for each instrument of each spacecraft. The data contained in this dataset contains the data taken by the Giotto RADIO SCIENCE EXPERIMENT (GRE). The dataset contains as well documentation included in the original disk. Remark that the catalogues are empty in this dataset, since there were no catalogues in the original disk.
