Top: Demonstration of compensating the number of planetes-imal counts missed due to the ancient family covering a large portion of the search area. Here, we show the V-shape corresponding to the newly detected family in this work. The black points are the identified planetesimals from Table B.2. The black square is an example case, whose count is increased in proportion to the amount of search area that was obscured by the family’s V-shape. Here, the counts will increase from one to three, with a 60% chance of being increased to four. See the text for more details. Bottom: Compensation was applied 50 times with Monte Carlo-style sampling and all iterations are over-plotted with highly transparent lines.
