4UO115- A SEARCH FOR TEV PHOTONS DURING 1989(63 REVISITED )

An analysis of 47 hours of data, collected by the Gulmarg gamma-ray te lescope during the period 27 September-30 October 1989, indicates the absence of a statistically significant DC signal from the x-ray binary pulsar, 4UO115+63, at photon energies greater than or equal to 4 TeV. An independent search, carried out fora pulsed signal in the same dat abase, using the well known Rayleigh power test, also does not yield e vidence for any episodic, or persistent-pulsed, gamma-ray emission fro m the source. An upper limit of 2.33 x 10(-11) photons cm(-2) s(-1) is placed at 99% confidence level on the steady gamma-ray flux from this transient x-ray binary system at photon energies > 4 TeV.
