Normalised individual IMF KDEs of the 33 groups (blue transparent curves), the mean-normalised IMF from our detections (blue solid curve), and from the S_lit groups (black). The dots with Poisson error bars show the mean-normalised histogram of the masses of the groups and the dashed curves show the log-normal and power-law parametrisations of the mean-normalised IMFs. The green curve shows the mean-normalised IMF of the synthetic sources. The thick blue transparent lines show the triple power law fitted to the mean-normalised IMF of our detections. The brown dashed line shows the typical IMF of the solar neighbourhood: Chabrier (2005) log-normal for m < 1 M_⊙ and Salpeter (1955) power-law for higher masses.
