J/A+AS/113/51 J/A+AS/113/51 Catalogue of associations IRAS and S stars P S Chen H Gao A Jorissen Astron. Astrophys. Suppl. Ser. 113 51 1995 1995A&AS..113...51C II/125 : IRAS Catalogue of point sources (IRAS-PSC) III/168 : General Catalog of S Stars, second edition (Stephenson 1984) catalogs infrared: stars stars: AGB, S 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.
