Table 3.

Fitting result of K − Pb corresponds to different combinations of the distance measurement.

Significance Groups Num β log α
1σ A 9 0.39
A,B 14 2.33
A,B,C 19 3.51

2σ A 5 0.82

3σ A,B,C 6 0.36

Notes. The different groups are denoted as follows: “A” corresponds to sources with a distance measured by the globular cluster; “B” is for sources with a distance measured by pulsar timing; and “C” corresponds to sources with a distance measured by the DM, and two systems with a distance measured by the globular cluster that do not have a not proper motion measurement also belong to Group C.
