摘要：
The performance of the EAS array at Kolar Gold Fields (working since 1984 and upgraded by 1987) is described. The array has been designed to search for sources of ultra high energy (UHE) photons. The array, the data recording and estimation of shower parameters are briefly described. The angular resolution of the array is discussed in detail. We demonstrate, using our data, that the shower front is not a plane and derive an expression for the correction to be applied to the observed time delays in each EAS before fitting a plane front. We suggest using an acceptance cone, dependent on the number of timing detectors used to estimate the arrival direction Of EAS, for point source searches.
