Notes. The luminosities of the pulsed emission L are calculated as with values for the distance d taken from the table, and the beaming fraction set to 1. F represent the pulsed flux. ^(a) Luminosities, fluxes, and efficiencies labeled with x are evaluated for the 2-100 keV band. ^(b) Luminosities, fluxes, and efficiencies labeled with are evaluated for the 0.1-10 GeV band. ^(c) The -ray energy flux of PSR B1509-58 in the 0.1-10 GeV band has been derived from the (total) photon flux values for the 100-300 and 300-1000 MeV bands as given in Kuiper et al. (1999) assuming a power-law shape with photon index of 2.5, and should be considered as an upper-limit to the pulsed flux of PSR B1509-58 in the 0.1-10 GeV band.
