摘　　要：本文通过对天体测量仪器光子计数模拟资料的处理,比较了13种不同的平滑模型和两种定心算法对最终精度的影响;提出了利用频率域滤波和修正矩方法相结合的最佳处理方法;并对比较结果进行了多方面的讨论。According to the processing of the analog data obtained with the photon counters on the astrometric instruments,the effects of thirteen kinds of smoothing models and two kinds of centering algorithms to the final accuracy are compared and an optimal method combining the filtering of the frequency domain with the modified moment is proposed.The compared results are discussed in many ways.
