Pulsar timing residual data

In the process of data generation, we first constructed the arrival time of each pulsar based on a standard timing model (including rotation frequency and higher-order derivatives).

On this basis, to study the detectability of transient gravitational wave burst events, we synchronously injected a gravitational wave burst signal with the same strain amplitude into the residual sequences of the six pulsars mentioned above. The signal exhibits a specific waveform in the time domain. By maintaining the consistency of injected amplitude in the data of 6 pulsars, a standardized testing benchmark is provided for verifying the signal.
