Abstract
A search for TeV gamma-rays from the isolated pulsar PSR1706-44 using the ground-based atmospheric Cerenkov imaging technique has been carri ed out. Analysis of data taken during 1993 and 1994 from the Universit y of Adelaide's 37 pixel Cerenkov imagine telescope, with special atte ntion paid to the effects of sky-noise differences between ON and OFF source regions, yielded an upper limit to the steady TeV gamma-ray emi ssion. The 3 sigma upper limit for energies above 0.5 TeV is 7.0(+/-0. 7) x 10(-11) photons cm(-2)s(-1), consistent with the previously repor ted detection above similar to 1 TeV for steady emission.
