||File from which to read atomic form factors. Defualt amounts to use the one shipped with McXtrace.
||Isotropic scattering factors (parameterized by q), or atom positions are specified for state 0.
||Isotropic scattering factors (parameterized by q), or atom positions are specified for state 1.
||Number of q-bins if F is to be computed from atom positions (Debye formalism).
||Where to read f1 and f2 factors from in order to handle absorption.
||Delay between the exciting event t=0. delay is negative, i.e. delta_t>0 means the exciting event happens before t=0.
||Mean fraction of molecules that get excited.
||Mean relaxation time (into state 0) of excited molecules.
||Which state is Molecule_2state in for t
||Minimum scattering angle off the optical axis.
||Maximum scattering angle off the optical axis.
||Minimum scattering angle around the optical axis.
||Maximum scattering angle around the optical axis.
||Radius of cylindrical of spherical sample.
||Height of rectangular or cylindrical sample.
||Width of rectangular sample.
||Depth (thickness) of rectangular sample.
||Concentration or packing factor of sample.
||Fraction of statistics devoted to sample direct (unscattered) beam.
||0: Assume that datafiles contains atom positions. 1: datafiles contains F vs. q data.
||Maximal energy for which scattering factors are computed. Must be larger than the maximal impinging energy.
