XM solution around HIP 36208 (Luyten’s star). Left: input candidate sources (green triangles) and isolated group of detections (input of the clustering solution), including those closer than 1.′′5 to these candidate sources (blue dots) and those without source candidates at a 1.′′5 distance (blue circles). The dashed green lines are the source candidates links (closer than 1.′′5). Right: XM resolution including the detections (blue dots; the yellow dot denotes double detections with low priority) and the new source propagated to the observation epoch (pink triangles). The grey area indicates the cluster we found. The isolated group of detections in the left panel includes 25 detections in the Gaia onboard magnitude range 7.75 < G < 9.39 and four source candidates in the Gaia magnitude range 8.46 < G < 8.51. The XM solution creates a unique source with a magnitude G = 8.31 corresponding to the mean of the Gaia onboard magnitude detection.
