The combination of ground-based astrometric compilation catalogues with the HIPPARCOS Catalogue II. Long-term predictions and short-term predictions
The combination of ground-based astrometric compilation catalogues, such as the FK5 or the GC, with the results of the ESA Astrometric Satellite HIPPARCOS produces for many thousands of stars proper motions which are significantly more accurate than the proper motions derived from the HIPPARCOS observations alone. In Paper I (Wielen et al. 1999, A&A 347, 1046) we have presented a method of comb...
متن کاملMagnitude systems in old star catalogues
Abstract. The current system of stellar magnitudes first introduced by Hipparchus was strictly defined by Norman Robert Pogson in 1856. He based his system on Ptolemy’s star catalogue ‘Almagest’, recorded in about 137 A.D., and defined the magnitude-intensity relationship on a logarithmic scale. Stellar magnitudes observed with the naked eye recorded in seven old star catalogues were analyzed i...

متن کاملExposing CSW Catalogues as Linked Data
The OpenGIS Catalogue Services (CS) specification defines a set of abstract interfaces for the discovery, access, maintenance and organization of metadata repositories of geospatial information and related resources in distributed computing scenarios, such as the Web. The CS specification also defines a HTTP protocol binding, which is called “Catalogue Services for the Web” or CSW. A fair descr...
متن کاملSemantic enrichment of standard-based electronic catalogues
Today, enterprises are facing serious interoperability problems concerning the exchange of electronic data. Due to the proliferation of terminology, organizations from similar business environments have trouble cooperating, and supply chains are experiencing difficulties exchanging electronically vital information, such as catalogue data. In order to solve this problem, standardization communit...
