specified observables.
Parameters
----------
dcs
data container(s), from which to extract density of states
as well as observables
temperatures
temperatures, at which to compute the averages
observables
observables, for which to compute averages; the observables
must refer to fields in the data container
boltzmann_constant
Boltzmann constant :math:`k_B` in appropriate
units, i.e. units that are consistent
with the underlying cluster expansion
and the temperature units [default: eV/K]
fill_factor_limit
use data recorded up to the point when the specified fill factor limit
was reached when computing averages; otherwise use data for the last
state
Raises
------
ValueError
if the data container(s) do(es) not contain entropy data
from Wang-Landau simulation
