The Henize sample of S stars - II. Data

This paper presents data collected on the Henize sample of 205 S stars: (i) CORAVEL radial-velocity data; (ii) photometric data in the UBV bands of th e Geneva photometric system; (iii) photometric data in the JHKL bands of th e SAAO photometric system; (iv) IRAS fluxes; (v) low-resolution spectra of 158 S stars. Close visual companions have been found for Hen 47, 94, 105 an d 155. Spectroscopic orbital elements are provided for Hen 2, 108, 121, 137 and 147. The analysis of these data is presented in a companion paper.
