[yt-dev] Issue #1345: Add "north_vector" to field parameters (yt_analysis/yt)

New issue 1345: Add "north_vector" to field parameters https://bitbucket.org/yt_analysis/yt/issues/1345/add-north_vector-to-field-p... Anonymous: When I try to add/create fields for my dataset, I cannot call: def _velocity_projected_north(field, data): nv = data.get_field_parameter("north_vector") ......... return v ds.add_field(('gas','velocity_projected_north'), function = _velocity_projected_north,units="cm/s", force_override = True) It would be great if north_vector is included in dataset Responsible: MatthewTurk
