Location of the two components in Integral of Motion (IoM) space. In the top panel, we plotted the total energy versus the z component of the angular momentum (L_z) for stars belonging to either component of the stream. The lower panel similarly shows the perpendicular component to the total angular momentum L_⊥ plotted against L_z. Though the narrow component seems less scattered in energy versus L_z, we see no significant separation between the narrow and broad components in integral of motion space.
