Notes. The first five columns give the pulsar names and discovery articles, their rotational periods (P), and Dispersion Measure (DM) values, and the Rotation Measure (RM) values from Dai et al. (2015) used for correcting the NUPPI data for Faraday rotation. The following columns give the observation epochs and durations, the numbers of pulse phase bins of the NUPPI profiles displayed in Figs. 3–6, and the signal-to-noise (S/N) ratios of the profiles, when calibrating the data using the SINGLEAXIS method of PSRCHIVE (“Orig. S/N”) and with the improved calibration method presented in Sect. 2.2 (“New S/N”). See Sect. 2.2 and Eq. (1) for details on the calculation of the S/N values.
