  Over the past six years, the Fermi Large Area Telescope has detected more
than 150 gamma-ray pulsars, discovering a variety of light curve trends and
classes. Such diversity hints at distinct underlying magnetospheric and/or
emission geometries. We implemented an offset-dipole magnetic field, with an
offset characterised by parameters epsilon and magnetic azimuthal angle, in an
existing geometric pulsar modelling code which already includes static and
retarded vacuum dipole fields. We use these different magnetic field solutions
in conjunction with standard emission geometries, namely the two-pole caustic
and outer gap models (the latter only for non-offset dipoles), and construct
intensity maps and light curves for several pulsar parameters. We compare our
model light curves to the Vela data from the second pulsar catalogue of Fermi.
We use a refined chi-square grid search method for finding best-fit light
curves for each of the different models. Our best fit is for the retarded
vacuum dipole field and the outer gap model.
