The UK ROSAT Deep Survey by McHardy, I, Jones, L, Merrifield, MR, Mason, K, Newsam, A, Abrahm, R, Dalton, G, Carrera, F, Smith, P, Rowan-Robinson, M, Wegner, G, Ponman, T, Lehto, H, Branduardi-Raymont, G, Luppino, G, Efstathiou, G, Allan, D, Quenby, J

“…We present a summary of the identification content of the UK ROSAT Deep Survey. The survey is based on a 115ksec PSPC observation and comprises a sample of 70 sources to a flux limit of 2 x 10(-15) ergs cm(-2) s(-1) (0.5-2 keV). …”
