Description:
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.
