  We develop a FORTRAN code to compute fluctuations in atomic condensates
(FACt) by solving the Bogoliubov-de Gennes (BdG) equations for two component
Bose-Einstein condensate (TBEC) in quasi two dimensions. The BdG equations are
recast as matrix equations and solved self consistently. The code is suitable
for handling quantum fluctuations as well as thermal fluctuations at
temperatures below the critical point of Bose-Einstein condensation. The code
is versatile, and the ground state density profile and low energy excitation
modes obtained from the code can be easily adapted to compute different
properties of TBECs -- ground state energy, overlap integral, quasi particle
amplitudes of BdG spectrum, dispersion relation and structure factor and other
related experimental observables.
