SMART MSP Census

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" (DOI: 10.1017/pasa.2025.10081).

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`.
