Thanks Matt!

From the line:

east_vector = np.cross(north_vector, normal_vector).ravel()

it seems the normal vector points out of the page (assuming East is to the right).

It's something of a free parameter, as unless you specify the "north"
vector it is determines by taking two cross products.  You can see how
it's determined in the file yt/utilities/orientation.py .
