SIMBAD references

As part of the preparation for the Hipparcos mission, we determined the positions of 96800 already listed stars and 21265 previously unlisted companions, using information gathered by the ESO Quick Blue Survey. B1950 and J2000 system coordinates are given for each star. The magnitudes and spectral types are given in addition to the exact date of the observation (approximately 1976). PPM, HIC, SAO, HD, CoD, CPD, CPC, ADS, IDS, BD, LHS and V* identifiers are given systematically whenever they exist as well as two supplementary identifiers selected from 43 other catalogues. Comments where necessary to complete the information. This catalogue is available from the Centre for Astronomic Data at Strasbourg.
