Three runs of LAAT (a–c) after fine-tuning the CMD selection between each run. The CMD refinement is shown in the first column and is applied before each LAAT iteration. Middle panels show the spatial distribution of the stars while left panels show their position in proper motion space. The upper row of the panels a–c shows the distribution of pheromone at the end of the run, while the lower row shows the remaining stars after enforcing a threshold on the pheromone quantity. Darker colors mark stars that accumulated higher quantities of pheromone, indicating regions of local alignment and density. In this way, a CMD cut is first performed, followed by finding a distribution of pheromone using LAAT and retaining stars that have accumulated a pheromone quantity that exceeds the given threshold. The CMD of the remaining stars is replotted and refined and the procedure is repeated until the stream is isolated from the majority of field stars. (a) First run of LAAT applied with a threshold of 30%. (b) Second run of LAAT applied with a threshold of 40%. (c) Third run of LAAT applied with a threshold of 50%.
