A first comparison with existing N-body models of the stream reveals some discrepancies, especially near the pericenter of the trailing arm and an underestimation of the total proper motion for the leading arm.Ĭonclusions: Our study provides a starting point for determining the variation of the population of stars along the stream, the distance to the stream from the red clump stars, and the solar motion. If you are working with motion-capture data and would like to bring point-cloud data into 3ds Max and then map the motion onto a CATRig, this topic can help. From these stars, we determine the proper motion along the Sagittarius stream, making it the proper-motion sequence with the largest span and continuity ever measured for a stream. Altogether, around 100 000 stars potentially belong to the stream as indicated by a coarse inspection of the color-magnitude diagrams. The 1500 peaks identified depict a continuous sequence spanning almost 2π in the sky, only obscured when the stream crosses the Galactic disk. Results: We find that for most of the sky patches, the highest intensity peaks delineate the path of the Sagittarius stream.

Motion Mapping is a projection mapping and video projection company that creates jaw-dropping displays and immersive visual experiences. Aims: We aim to measure the proper motion along the Sagittarius stream, which is the missing piece in determining its full 6D phase space coordinates. ![]()
