Pulsar orientation angles for the two branches of our geometry fit. The pulsar rotates counter-clockwise, and the spin axis is shown by the vertical arrow. The shorter green arrows show the magnetic axis, and the brown arrows show the LOS. The branches are labelled outside traverse and inside traverse to match the notation of DR01; inside/outside refers to the relative position of the LOS direction with respect to the smaller angle between the spin and magnetic axes. We follow the definition of (α, β) in EW01, which is different from the one used by DR01. The conversion between the two notations is given in Table 2.
