Pulse template establishment with the consideration of the directional error of pulsar.

A pulse template establishment method considering the directional error of the pulsar is proposed in this paper. This method folds the series of photon time of arrival (TOA) of symmetric time intervals to reduce the impact of directional error on pulse template. Firstly, the characteristic of this error is analyzed. And then, its analytical formula of the average value for a whole year is derived as well as that for arbitrary time interval. Finally, the simulated and real data are employed to investigate the performance of the proposed method. Results have shown that this method can establish a relative high-accuracy pulse template.
