Gaia DR3 CMD for M35. Left: the grey points represent stars in the vicinity of M35 that Clusterix 2.0 classified as cluster members. We have carried out a subsequent analysis removing some stars whose parallaxes and/or proper motions were very different from those of M35 (Gaia Collaboration 2018). Candidate members of the cluster in our sample are shown in red, while the black circles are stars whose photometry suggests they are not members of M35. We used optical and infrared photometry published in Bouy et al. (2015) to classify eight other photometric outliers as non-members. Right: a zoomed-in version of the CMD highlighting the multiple systems in our sample. The squares are potential wide binaries identified by Gaia, triangles are spectroscopic binaries, and diamonds are binary systems found by Jeffries et al. (2021). Note that neither CMD has been corrected for reddening.
