  Using the high statistics datasets of the HotQCD Collaboration, generated
with the HISQ (2+1)-flavor action for light and strange quarks, and treating
the charm sector in the quenched approximation, we analyze the second and
fourth order cumulants of charm fluctuations and the correlations of charm with
lighter conserved flavor quantum numbers. We can make use of a factor 100
larger statistics on ${N_\tau =8}$ lattices which never have been used in
studies of charm fluctuations. Analyzing correlations of charm fluctuations
with baryon number and electric charge fluctuations we can project onto charmed
baryon and meson correlations and compare results with quark model extended
hadron resonance gas model calculations. We aim at a precise determination of
the dissociation temperature of charmed hadrons and will probe the sensitivity
of the fluctuations observables to the presence of multiple-charmed baryons.
