The data of the article "Pulsar Time and Atomic Frequency standards Combined Time-scale"

According to the principle of combined smoothing filter, the frequency difference of CPA-TAI is equal to the frequency difference between the atomic frequency reference smoothed by the combined smoothing filter and TAI. The frequency stability and accuracy of CPA are very close to the widely used Earth time, therefore, CPA can also be used as Earth time. This dataset mainly consists of two files.

File 1 is the comprehensive pulsar time and TAI clock bias (EPT62-TAI) data ("clock62"), as shown by the blue line in Figure 1 of this article (60 rows and 3 columns): the first column is the reduced Julian day (MJD), the second column is the clock bias (unit: μs), and the third column is the uncertainty of the clock bias (unit: μs). File 2 is the data smoothed with a smoothing filter ("clock62cp") (382 lines and 3 columns): the first column is the reduced Julian day (MJD), the second column is the CAP-TAI clock bias (unit: μs), as shown by the red line in Figure 6 of this article, and the third column is the frequency difference of CPA-TAI (unit: μ s/d), as shown by the red line in Figure 5 of this article.

Figures 4 and 7 in the article are calculated using data from files 1 and 2, with the aim of evaluating the performance of these two subsets of data. Therefore, relevant data will not be provided.
