Profile of likely Jhelum members changes along the stream. Panels show 5° wide regions along the stream, with the location in ϕ1 (indicated at the top) growing from left to right. Between −3° < ϕ1 < 2°, only a narrow component of the stream is present, while in the next ϕ1 bin, 6° < ϕ1 < 11°, the stream features both the narrow and the wide component. Further along the stream, 15° < ϕ1 < 20°, the stream consists of two narrow components separated by a gap, while at the trailing end, 20° < ϕ1 < 25°, the gap vanishes and the stream appears as a single, wide feature.
