Best-fit parameters of an asymmetric Lorentzian model for the P2 peak, obtained from the Fermi-LAT and H.E.S.S. II data in different energy ranges, as part of a three-component function fit to the Vela pulsar light curve (see text).

Notes. Parameters are the fitted position, ΦP2, the leading (or inner) edge width, σL, and the trailing (or outer) edge width, σT. An additional Gaussian component with position, ΦG, P2, and width, σG, P2, is included for the fit to the H.E.S.S. II full energy range light curve. The energy ranges and corresponding average energies are also given (see text).
