SIMBAD references

Cross identifications between the General Catalogue of Galactic S Stars (GCGSS), the IRAS Point Source Catalogue (PSC), and the Guide Star Catalogue (GSC) are presented. The purpose of the present catalogue is i) to provide a clean sample of S stars with far-IR data, and ii) to provide accurate GSC positions for S stars, superseding those listed in the GCGSS. The IRAS colour-colour diagram and the galactic distribution of S stars associated with an IRAS source are presented. Several S stars having extended images in at least one IRAS band have also been identified.
