only, if it moves off of crosshairs in two or more images, if the subject is not round in Pan-STARRS, SkyMapper, or 2MASS images, if it becomes extended beyond the outer circle in WISE images, and if two or more images show objects between the inner and outer circles. The ideal target is classified as a "good candidate," and is further vetted by the advanced research group into a list of "debris disk of interest" (DDOI) candidates. Particular interest is paid to good candidates that have two or more images where objects other than the subject are present within the inner circle only.

W1200-7845 is also very young, with measurements putting it at about 3.7 million years old, meaning that—along with its relatively close proximity—it could serve as a benchmark for future studies of brown dwarf system formation.
