This type of data contains information about the pulse profile in dimensions such as observation time, frequency, polarization, and pulse phase. In order to improve the signal-to-noise ratio of pulse profiles and generate one-dimensional integral profiles suitable for time measurement analysis, the PSRCHIVE software package can be used to perform time, frequency, and polarization superposition processing on the data.

Overlay data on all frequency channels, time stack all sub integrals, and stack polarization channels. For each FTp observation profile, the pat program in PSRCHIVE can be used to match it with a standard template, thereby obtaining the observed pulse arrival time of the pulsar. Finally, Tempo2 can be used to obtain the final phase linked time solution.
