Description
-----------
 
    This bank contains constants used by the FTK energy fitter

    There are four DFTK banks
    1) This bank contains the reflection probability of a photon
       given the incident cos(theta) and wavelength
    2) This bank contains the probability of a photon 
       reflecting into angle cos(theta_prime) and phi given an incident 
       angle cos(theta)
    3) This bank contains the parameters used for the lognormal function
       used to find the number of Cerenkov photons for a given energy
    4) This bank contains the parameters used for the cos(alpha) 
       distributions for the direction of the photon with respect to the 
       electron direction
