VizieR Online Data Catalog: UTMOST pulsar timing programme. I. (Jankowski+, 2019)
Abstract
We present updated astrometric ephemerides and rotational parameters for 205 radio pulsars, of which 8 are in binary systems, and 197 are isolated. For 60 of them, we publish inferred proper motions and transverse velocities, and for all of them, we report band-integrated flux densities, modulation indices and pulse widths at 50 and 10 per cent maximum at a frequency of 843 MHz. Our measurements are based on up to daily observations with time spans of 1.4 to 3yr performed at the refurbished Molonglo Observatory Synthesis Radio Telescope (MOST), a radio interferometer located in Australia.
In table 3, we list the pulsar names (J2000), the proper motions in right ascension and declination, proper motion measurements from the literature where available, the maximum time spans between position measurements, the number of positions in the fit, the references for the literature proper motions, the pulsar distances and their transverse velocities. In table B1, we report the pulsar names (J2000), their positions referenced to the ICRF, their spin frequencies and first temporal derivatives, the root mean square timing residuals in us and as a fractions of the pulsar periods, the number of pulse arrival times, the reduced chi2 and degrees of freedom of the fits, the timing baselines and a flag whether we corrected the pulse arrival times for underestimation. Table B1 shows the results for 8 pulsars in binary systems. Table B2 reports the results for 197 isolated pulsars, in a format analogue to the one of table B1. In table C1, names (J2000), whether they have interpulses, their band-integrated flux densities at 843MHz, their robust modulation indices and their pulse widths at 50 and 10 per cent maximum. The period, position and dispersion measure determination epoch is set to MJD 57600 for all pulsars. We report all uncertainties at the 1 sigma level. (4 data files).- Publication:
