The Ariel V (3A) catalogue of X-ray sources. II.

This paper forms the second part of the Ariel V 3A catalogue and covers all the sky outside the galactic plane ( |b| > 10°). it is based on all the data collected by the Sky Survey instrument on the Ariel V satellite during its 5 yrs in orbit. it covers 90 per cent of the high latitude sky down to ∼0.8 SSI count s^-1 and contains 142 sources. The main difference from the 2A catalogue is the far greater number of identifications with stars, and, to a lesser extent, with active galaxies. The number of identifications with clusters of galaxies has hardly changed. We suspect that many of the unidentified sources will eventually be identified with cataclysmic variables.
