  We calculate numerically and analytically the fluctuations of the fermionic
condensate and of the number of particles above the condensate for systems of
constant density of states. We compare the canonical fluctuations, obtained
from the equivalent Bose condensate fluctuation, with the grandcanonical
fermionic calculation. The fluctuations of the condensate are almost the same
in the two ensembles, with a small correction comming from the total particle
number fluctuation in the grandcanonical ensemble. On the other hand the number
of particles above the condensate and its fluctuation is insensitive to the
choice of ensemble.
