Notes. Ė and BLC for pulsars with proper motion measurements are Doppler corrected as in 2PC, with uncertainties from the proper motions and distances. The first spectral uncertainties are statistical, the second are systematic. The luminosity assumes a beaming factor fΩ = 1. Profile fit types – G: Gaussian; G2: 2-sided Gaussian; L: Lorentzian; L2: 2-sided Lorentzian.
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.
Initial download of the metrics may take a while.
