Notes. Given are the pulsar name in J2000 coordinates, the pulse period P, the catalogue DM, the ecliptic latitude β, the total time span of the observations, the number of observations with GLOW and the LOFAR Core Nglow and Ncore, the median frequency-integrated ToA uncertainty, the median uncertainty of individual DM measurements, the median reduced χ2 of the individual DM fits, and the number of frequency channels in each observation. The last column shows whether the pulsar is used in different PTA projects (i.e. E: European Pulsar Timing Array, EPTA; P: Parkes Pulsar Timing Array, PPTA; N: North American Nanohertz Observatory for Gravitational Waves, NANOGrav; see Verbiest et al. 2016; Arzoumanian et al. 2018). A pulsar observed by any of the PTAs is also used by the International Pulsar Timing Array (IPTA). (*) For these pulsars, an analytic standard template without frequency resolution was used. (a) PSR B1257+12 (b) PSR B1855+09 (c) PSR B1953+29.
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
