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 html, body, table, thead, input, textarea, select {color: #bab5ab!important; background: #35393b;} input[type="text"], textarea, select {color: #bab5ab!important; background: #35393b;} [data-darksite-inline-background-image-gradient] {background: linear-gradient(rgba(0, 0, 0, 0.5), rgba(0, 0, 0, 0.5))!important; -webkit-background-size: cover!important; -moz-background-size: cover!important; -o-background-size: cover!important; background-size: cover!important;} [data-darksite-force-inline-background] * {background-color: rgba(0,0,0,0.7)!important;} [data-darksite-inline-background] {background-color: rgba(0,0,0,0.7)!important;} [data-darksite-inline-color] {color: #fff!important;} [data-darksite-inline-background-image] {background-image: linear-gradient(rgba(0,0,0,0.3), rgba(0,0,0,0.3))!important}
