Pulsar geometry and emission modeling for PSR J0248+6021. Green contours show the rotating vector model fit to the radio polarization data (contours at δ(χ²/d.o.f.) =  +0.25,    +0.5 above the minimum χ²/d.o.f. of 1.6). The color backgrounds are χ₃ maps of the fit to the observed  >100 MeV pulse profile to the outer gap model (left), the two-pole caustic model (middle), and the separatrix layer model (right), for different values of the magnetic inclination, α, and the minimum angle to the line-of-sight, ζ (Romani & Watters 2010). Each panel has the same color scale, where dark colors represent better fits. The preferred models lie along the green RVM-selected band.
