[yt-users] Radial velocity Projections

Hi All,

I was trying to make an OffAxis radial projection. Naively using

 proj = OffAxisProjectionPlot(pf, L, "RadialVelocityKMS", center='max',
width=(width, 'pc'),
                                     depth=depth)

fails with a message of type

yt.data_objects.field_info_container.NeedsParameter: (['center'])


The RadialVelocity probably isn't the field to use here and requires some
manipulation to be a quantity suitable for plotting.

Any suggestions on the best way forward would be much appreciated.

Cheers,
John
