Notes. NS mass, radius, and spin frequency are fixed at M = 1.4 M⊙, R = 12 km, ν = 401 Hz. These parameters, as well as Model 1 parameters, are selected based on the SAX J1808.4−3658 pulsar and expected values for canonical NSs. The errors represent the 68% credible interval. Additional parameters χ and Δϕ are the position angle of the pulsar rotation axis and the phase shift, respectively. As before, i is inclination, θ is co-latitude of the spot, Te and Tbb are the temperatures of the electron in the slab and seed photons, respectively, and τT is the Thomson optical depth of the slab. Values are averaged over two data realizations for each scenario.
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.
