Name  Unit  Description  Default 
form_factors  ( ) File from which to read atomic form factors. Defualt amounts to use the one shipped with McXtrace.  "FormFactors.txt"  
state_0_file  ( ) Isotropic scattering factors (parameterized by q), or atom positions are specified for state 0.  NULL  
state_1_file  ( ) Isotropic scattering factors (parameterized by q), or atom positions are specified for state 1.  NULL  
nq  ( ) Number of qbins if F is to be computed from atom positions (Debye formalism).  512  
material_datafile  ( ) Where to read f1 and f2 factors from in order to handle absorption.  "Be.txt"  
delta_t  (s) Delay between the exciting event t=0. delay is negative, i.e. delta_t>0 means the exciting event happens before t=0.  100e9  
excitation_yield  ( ) Mean fraction of molecules that get excited.  0.2  
t_relax  (s) Mean relaxation time (into state 0) of excited molecules.  100e9  
initial_state  ( ) Which state is Molecule_2state in for t  0  
psimin  (rad) Minimum scattering angle off the optical axis.  0  
psimax  (rad) Maximum scattering angle off the optical axis.  M_PI_2  
etamin  (rad) Minimum scattering angle around the optical axis.  M_PI  
etamax  (rad) Maximum scattering angle around the optical axis.  M_PI  
radius  (m) Radius of cylindrical of spherical sample.  0  
yheight  (m) Height of rectangular or cylindrical sample.  0  
xwidth  (m) Width of rectangular sample.  0  
zdepth  (m) Depth (thickness) of rectangular sample.  0  
concentration  (m) Concentration or packing factor of sample.  1  
p_transmit  (m) Fraction of statistics devoted to sample direct (unscattered) beam.  0.1  
q_parametric  ( ) 0: Assume that datafiles contains atom positions. 1: datafiles contains F vs. q data.  0  
Emax  ( ) Maximal energy for which scattering factors are computed. Must be larger than the maximal impinging energy.  80
