The Bordeaux observatory astrometric group has performed significant efforts to produce and exploit large data base surveys. This effort has been realized to extend and densify the ICRS materialized by Tycho2 catalogue. This effort concerns the systematic re-observation of the Bordeaux Carte du Ciel zone with the Bordeaux automatic CCD meridian...

We present a proper motion catalogue of 2670974 stars, covering the declination zone +11°<=?<=+18°. Proper motions were derived from the comparison of the positional M2000 catalogue (systematic observations of the Bordeaux Carte du Ciel Zone with the meridian circle, completed in 2000) with positions derived from the reduction of 512 Carte du...

Context: .This work is part of a program of proper motion measurements in the Bordeaux Carte du Ciel zone.Aims.We present the CdC2000 catalogue issued from the reduction of the complete Bordeaux Carte du Ciel zone observed at the begining of last century with the Bordeaux astrograph.Methods.Plates have been individually reduced using the...
