Caption: Figure 25.

Sky trajectory of a representative trans-Neptunian object (TNO) discovered in the NGVS. The crosses mark the locations where the TNO was detected, with the line showing the complete motion of the object over the 2009–2011 observing seasons (moving from west to east). Since the NGVS imaging (shaded area) is being acquired over multiple years, it enables the detection of the moving source in multiple observing seasons. The orbital parameter uncertainty on this source is less than 1%, which is adequate for orbit classification.
