V/126                MEGA-H proper motion catalog             (Kharchenko, 2004)

Compiled catalogue of stellar proper motions in the Hipparcos system in the MEGA program areas. Kharchenko N.V. <Kinematika Fiz. Nebesn. Tel., 20, 366 (2004)> =2004KFNT...20..366K
ADC_Keywords: Combined data ; Positional data ; Proper motions ; Photometry, UBV ; Cross identifications Description: The catalogue MEGA-H is a result of a merging of star lists from the catalogue of stellar proper motions with respect to galaxies in 47 selected areas near the Main Meridional Section of the Galaxy (MEGA-G) (Kharchenko 1987) and from All-sky Compiled Catalogue of 2.5 Million Stars (ASCC-2.5) (Cat. I/280). Proper motions from the catalogue MEGA-G were reduced to the Hipparcos system by means of common with the ASCC-2.5 stars. The compiled proper motions in the Hipparcos system and their standard errors were computed as the weighted means. Equatorial coordinates are reduced to the equinox J2000 and epoch 1991.25. The catalogue MEGA-H contains 18169 stars. Stars are sorted in right ascension J2000 order. File Summary:
