J/A+AS/136/307 Coma Berenices astrometric catalogue (Abad+ 1999) ================================================================================ An astrometric catalogue for the area of Coma Berenices Abad C., Vicente B. =1999A&AS..136..307A (SIMBAD/NED BibCode) ================================================================================ ADC_Keywords: Magnitudes, photographic ; Positional data ; Clusters, open ; Proper motions Keywords: astrometry - catalogues - methods: data analysis - open clusters: Coma cluster Abstract: A catalogue of stellar positions and proper motions down to the 14th photographic magnitude in the area of the open cluster in Coma Berenices is compiled from data of 12 different sources. The accuracy of the proper motion data is comparable to that of the Hipparcos Catalogue (Cat. ).
