- Michael Keith: Keith performed some of the observations included in the PPTA subset presented in this paper. He participated to the frequentist analysis (S2.1), which underpins the main results about the pulsar-based time-scale. In particular, he has developed key TEMPO2 updates that provided a more stable least-square solver, without which it would be impossible to obtain some of the timing solutions and also enabled more realistic errors. He has also implemented several fitting routines used for the analysis. Finally, he manages TEMPO2 clock files, which keep track of local anomalies with maser clocks crucial to achieve timing precision.
