A search for TeV γ-rays from the isolated pulsar PSR 1706-44 using the ground-based atmospheric Cerenkov imaging technique has been carried out. Analysis of data taken during 1993 and 1994 from the University of Adelaide's 37 pixel Cerenkov imaging telescope, with special attention paid to the effects of sky-noise differences between ON and OFF source regions, yielded an upper limit to the steady TeV γ-ray emission. The 3σ upper limit for energies above 0.5TeV is 7.0(±0.7)x10^–11 photons/cm²/s, consistent with the previously reported detection above ∼1TeV for steady emission.
