Description
We present the SHEEP survey for serendipitously detected hard X-ray sources in ASCA GIS images. In a survey area of ~40deg^2^, 69 sources were detected in the 5-10keV band to a limiting flux of ~10^-13^ergs/cm^2^/s. The number counts agree with those obtained by the similar BeppoSAX High-Energy Large Area Survey (HELLAS), and both are in close agreement with ASCA and BeppoSAX 2-10keV surveys. Spectral analysis of the SHEEP sample reveals that the 2-10 and 5-10keV surveys do not sample the same populations, however, as we find considerably harder spectra, with an average {Gamma}~1.0, assuming no absorption.
