Description

Data Release for the SMART MSP Census

This record contains data products associated with Lee et al. (2025), "The Southern-sky MWA Rapid Two-metre (SMART) pulsar survey—III. A census of millisecond pulsars at 154 MHz" (to be published in the Publications of the Astronomical Society of Australia).

Tabulated Data

The data from Tables 1 and 2 are provided as a single table with 40 rows in ECSV format, which can be parsed by Astropy. The columns are described below.

Column Name(s) Units Description
PSRJ none The pulsar name (J2000)
PSRB none The pulsar name (B1950)
GL, GB deg The Galactic longitude and latitude
P0 ms The spin period (rounded to 3 d.p.)
DM, DM_ERR pc / cm3 The dispersion measure
S154, S154_ERR mJy The mean flux density at 154 MHz
BINARY none The binary system/companion type
EPOCH_MJD days The Modified Julian Date of the observation
OBSID none The MWA observation ID
TOBS min The integration time
OFFSET deg The mean angular offset of the pulsar from the pointing centre during the observation
DET none A semicolon-separated list of low-frequency telescopes with previous detections of the pulsar
RM_OBS, RM_OBS_ERR rad / m2 The observed profile-averaged rotation measure
RM_IONO, RM_IONO_ERR rad / m2 The estimated ionospheric rotation measure
RM_IISM, RM_IISM_ERR rad / m2 The ionosphere-corrected profile-averaged rotation measure
RM_MKT, RM_MKT_ERR rad / m2 The rotation measure from MeerKAT reported in Spiewak et al. (2022) (doi: 10.1017/pasa.2022.19)
RM_PKS, RM_PKS_ERR rad / m2 The rotation measure from Murriyang/Parkes reported in Dai et al. (2015) (doi: 10.1093/mnras/stv508)
Z_MKT, Z_PKS none The z-score of the reference RMs relative to the MWA RMs
SCAT_FLAG none A flag indicating if the mean flux density may be underestimated due to interstellar scattering
LOW_RM_FLAG none A flag indicating if the observed RM is within the zero-peak of the Faraday dispersion function

PSRCHIVE Archives

The folded data cubes are provided in PSRCHIVE format as Stokes parameters with 5-s subintegrations and 160-kHz subbands (or 320-kHz for J0437-4715, J2241-5236, and J2256-1024). The data have been provided with the maximum phase resolution, even for low-S/N detections, so the user can downsample based on their needs. For pulsars with RM measurements, the Faraday rotation has been removed and the RMs are stored in the headers. The archives have not been flux calibrated.

ASCII Profiles

The full-Stokes integrated pulse profiles are provided in ASCII format, produced by the PSRCHIVE command `pdv -ZKt`.
