Titles: DFTK: Energy fitter Data constants ===================================== Contact: M. Dunford, Penn Revision History:- ================ 5.01 M. Dunford First version. Titles Files ------------ ftk_data.dat Verification ------------ 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 Data Words --------- Data types: B(bit), I, F, D(double), H(hollerith 4 char) Fixed length Database Header.
