New issue 787: particle_specific_angular_momentum fields not working https://bitbucket.org/yt_analysis/yt/issue/787/particle_specific_angular_mom...

Britton Smith:

In the unitrefactor, running this script: http://paste.yt-project.org/show/4327/ gives the following:

I am able to grab the particle_positions on their own for a data object, but not within this field.
