Due to an error at the Press, in Table 1 data are incorrect for HUDF 4650 for the J, F160W, K, and m bands, and for all galaxies in the last two columns, m(8.0 m) and MIPS (24 m) (which incorrectly repeat previous columns). The correct full table is given here.The Press sincerely regrets this error.

Centaurus X-3 is a well studied high-mass accreting X-ray binary and a variable source of high-energy gamma rays with energies from 100 MeV to 1 TeV. Previous results have suggested that the origin of the gamma rays is not the immediate vicinity of the neutron star but is sited in the accretion disk, perhaps in an accretion wake. The Durham Mark 6 gamma-ray telescope has been used to measure the gamma-ray Ñux from Centaurus X-3 with much higher sensitivity than previous ground-based measurements. The Ñux above D400 GeV was measured to be (2^0.3) ] 10~11 cm~2 s~1 and appears constant over a period of 2È3 months. In 10 hours of observations there is no evidence for periodicity in the detected gamma rays at the X-ray spin period either from a site in the region of the neutron star or from any other potential site in the orbit.
