The Critical Evaluation of Stellar Datag the Goddard Cross Index of eleven star catalogues are outlined as one example of how star catalogues can be compared using computers. The classical approach to evaluating data critically is reviewed and the types of question one should ask and answer for particular types of data are listed.

The Use of Standardized Data Formats with the Westerbork Radio Telescopeess of the program. Transportation of data between observatories is done via magnetic tape with the same standard format. For data transportation to observatories not normally using Westerbork information a common tape format has been developed. Suggestions to alleviate problems with this data transfer are discussed.作者: Baffle 時間: 2025-3-24 14:46 作者: BOGUS 時間: 2025-3-24 15:02
