    • Automated Reduction and Calibration of SCUBA Archive Data Using ORAC-DR 

      Jenness, T.; Stevens, J. A.; Archibald, E.N.; Economou, F.; Jessop, N.; Robson, E.I.; Tilanus, R.P.J.; Holland, W.S. (Astronomical Society of the Pacific, 2001)
      The Submillimetre Common User Bolometer Array (SCUBA) instrument has been operating on the James Clerk Maxwell Telescope (JCMT) since 1997. The data archive is now sufficiently large that it can be used for investigating ...

    • Dust, Gas, and the Evolutionary Status of the Radio Galaxy 8C 1435+635 at z = 4.25 

      Ivison, R.J.; Dunlop, J.S.; Hughes, D.H.; Archibald, E.N.; Stevens, J. A.; Holland, W.S.; Robson, E.I.; Eales, S.; Rawlings, S.; Dey, A.; Gear, W.K. (1998)
      We present the results of new rest-frame far-IR observations of the z\4.25 radio galaxy 8C 1435]635, which not only conÐrm that it contains an enormous quantity of dust (as Ðrst inferred from its millimeter-wave detection ...

    • On the atmospheric limitations of ground-based submillimetre astronomy using array receivers 

      Archibald, E.N.; Jenness, T.; Holland, W.S.; Coulson, I.M.; Jessop, N.; Stevens, J. A.; Robson, E.I.; Tilanus, R.P.J.; Lightfoot, J.F. (2002-10)
      The calibration of ground-based submillimetre observations has always been a difficult process. We discuss how to overcome the limitations imposed by the submillimetre atmosphere. Novel ways to improve line-of-sight opacity ...

    • Towards the automated reduction and calibration of SCUBA data from the James Clerk Maxwell Telescope 

      Jenness, T.; Stevens, J. A.; Archibald, E.N.; Economou, F.; Jessop, N.; Robson, E.I. (2002-10)
      The Submillimetre Common User Bolometer Array (SCUBA) instrument has been op- erating on the James Clerk Maxwell Telescope (JCMT) since 1997. The data archive is now sufficiently large that it can be used to investigate ...
