Data table and PSRFITS-format files associated with Spiewak et al. 2022, "The MeerTime Pulsar Timing Array -- A Census of Emission Properties and Timing Potential" (doi:10.1017/pasa.2022.19). The zipped tar file contains one PSRFITS-format file per pulsar, containing a profile, summed from multiple observations with varying lengths, with 1024 phase bins across the profile, 1 subintegration, 8 frequency channels across the 775.75-MHz band, and 4 polarization channels (with the up-to-date rotation measures and dispersion measures in the headers).
The columns in the data table (in csv format) are as follows:
PSRJ : the pulsar name (J2000)
PTA_SCR : boolean indicating whether the pulsar is part of the MPTA
REF_SH : short form of the reference (psrcat-style)
GL, GB : Galactic longitude and latitude
P0, P1 : pulse period and period derivative in (s) and (s/s), respectively
DM, DM_ERR, DMEPOCH : the dispersion measure of a single epoch, with 1-sigma uncertainty, and the MJD for that epoch
RM, RM_ERR : the rotation measure, as described in the paper, with uncertainty
RM_SNG : boolean indicating whether the RM was measured from the summed archive (True indicates the RM_ERR is the 1-sigma uncertainty from `rmfit` and False indicates the RM_ERR is the standard deviation of all measured RMs after outlier removal)
L_FRAC, L_FRAC_ERR : the fractional linear polarization and uncertainty
V_FRAC, V_FRAC_ERR : the fractional circular polarization and uncertainty
ABS_V_FRAC, ABS_V_FRAC_ERR : the fractional absolute circular polarization (from `psrchive`) and uncertainty
TOA_ERR_NEW : the median ToA uncertainty, as described in the paper
SPIND, SPIND_ERR : the spectral index from a power law fit to the flux density per band and uncertainty
NOBS : number of unique observations of the pulsar included in this analysis
S1400, S1400_ERR : the flux density at 1400 MHz from a power law fit to the flux density per band, and uncertainty
FLUX_n_VAL, FLUX_n_ERR, FLUX_n_FRQ : flux density information per frequency band (n=0-7), the mean value, the formal error on the mean, and the mean frequency of the band
