Mass distribution from FLAME compared with a Kroupa (2001) IMF. For each of the 44 open clusters from Gaia Collaboration (2018b), we plot (grey) the recovered mass distributions from FLAME estimates. We highlight the overall median and [16, 84th] percentile interval in black. For reference, we plot in red the expected shape of masses drawn from a Kroupa IMF accounting for the limited number of identified members. Because of the noise of low number-statistics, we expect significant scatter from cluster to cluster. The low-mass end is affected by the Gaia selection function.
