Proper Motions
Scientific paper
GPM1 is the first version of the General Compiled Catalogue of Absolute Proper Motions for a sample of HIPPARCOS stars, derived with respect to galaxies within the plan called Catalogue of Faint Stars (KSZ, Deutch A.N., 1952IAUT....8..789D). The programme was proposed for several observatories of the former Soviet Union, China, Rumania and Spain. There are some resulting individual catalogues of absolute proper motions of stars compiled at five observatories (Kiev, Pulkovo, Moscow, Tashkent and Shanghai). The principal aim of the GPM1 construction was to provide absolute proper motions of stars to determine the rotation of the HIPPARCOS system. The GPM1 catalogue comprises absolute proper motions for 977 stars in 180 areas north of -25 degrees of declination. The mean square error is 8mas/yr on average. The standard errors differ from one star to another one depending on the number and quality of individual catalogues. They have been computed and presented for each star. For a single GPM1 field the absolute zero-point error of linking proper motions to the galaxies is 3mas/yr on average. The error of such a kind depends on the number and compactness of the galaxies available in each field. In addition to absolute proper motions and their mean errors, the catalogue gives the following data for each star: right ascension, declination, epoch for position, V-magnitude and number, copied from HIC. The stars were also identified with the objects of the Smithsonian Astrophysical Observatory Star Catalogue (SAO) list. Positions are given for equator and equinox J2000.0 on the system of FK5. They were presented to identify the GPM1 stars with those from other catalogues. The data file is sorted by J2000.0 right ascensions. (1 data file).
