Notes. We show the total mass (ℳ), the mass into stars more massive than
ma (Ma), the total number of
stars (),
the number of stars more massive than ma
(Na), the estimation of the mean mass for stars more
massive than ma (
),
and the logarithm of the probability that a cluster with
stars following the assumed IMF would have Na stars with
mass equal or larger than ma divided by the maximum of
such distribution ().
The ma value is set to
0.5 M⊙.
