Fundamental data for southern stars (First list)

Newly determined radial velocities are given for 25 IAU standard velocity stars and 343 other stars south of - 26 . Many nearby stars and stars of high velocity are included in this list. Magnitudes and colours on the Johnson B, v system and spectral types on the MK system have been determined for all the stars in the main list. Diagrams showing the relation between absolute magnitude, spectral type and colour index are given for the stars with known trigonometrical parallaxes and from these are deduced photometric parallaxes for 142 stars of luminosity class V. Space coordinates and space motions have been computed for these stars.
