| Abstract | 在已有脉冲星时频率稳定度σZ算法基础上,提出了针对长时间跨度计时观测数据缺失(gap)的脉冲星时稳定度的处理方法,并以该类典型的脉冲星J1857+0943于帕克斯天文台PARKES的实测数据为例,给出稳定度计算结果并讨论,简介了计时软件包Tempo2得到最小残差的拟合过程,并以Tempo2处理后的数据作为输入,由其时间尺度结果引发对Tempo2处理脉冲星时间尺度的相关分析与讨论,介绍了含gap的脉冲星观测数据在综合脉冲星时算法中的应用。 |
| Other Abstract | Based on the known stability algorithm σZ of pulsar time, the method of dealing with pulsar time with gaps of long time spans has been advanced, and the result of stability has been showed with related discussion taking PARKES’observation data of the typical pulsar J1857 + 0943 as example. The fit process of the timing software Tempo2 in getting the minimum time residuals was briefly introduced, making the simulated data as input, the analysis and discussion about the disposal of pulsar time scales with Tempo2 has been provided. At last, the application of timing data with gap in the algorithm of ensemble pulsar time was complemented. |
