VHE gamma rays from PSR B1706-44

Observations made with the University of Durham Mark 6 atmospheric Cerenkov telescope confirm that PSR B1706-44 is a VHE γ-ray emitter. The γ-ray flux has been measured at 250 GeV, and suggests a spectral slope that is consistent with extrapolation from the sub-10 GeV region. There is no indication from our dataset that the VHE γ-rays are pulsed, in contrast to the findings at <20 GeV, which indicate that 100% of the flux is pulsed.
