 * reflections: [str] Input file for reflections (LAZ LAU CIF, FullProf, ShelX). Use only incoherent scattering if NULL or "".
 *
 * Optional parameters:
-* d_phi:       [deg] Angle corresponding to the vertical angular range to focus to, e.g. detector height. 0 for no focusing.
+* barns:         [1] Flag to indicate if |F|^2 from 'reflections' is in barns or fm^2, (barns=1 for laz/cif, barns=0 for lau type files).
+* concentric:    [1] Indicate that this component has a hollow geometry and may contain other components. It should then be duplicated after the inside part (only for box, cylinder, sphere).
 * d_omega:     [deg] Horizontal focus range (only for incoherent scattering), 0 for no focusing.
-* tth_sign:      [1] Sign of the scattering angle. If 0, the sign is chosen randomly (left and right). ONLY functional in combination with d_phi and ONLY applies to bragg lines.
-* focus_flip:    [1] Controls the sense of d_phi. If 0 d_phi is measured against the xz-plane. If !=0 d_phi is measured against zy-plane.
-* tth_sign:      [1] Sign of the scattering angle. If 0, the sign is chosen randomly (left and right).
-* pack:          [1] Packing factor
+* d_phi:       [deg] Angle corresponding to the vertical angular range to focus to, e.g. detector height. 0 for no focusing.
 * delta_d_d:     [1] Global relative Delta_d/d spreading when the 'w' column is not available. Use 0 if ideal.
+* density:  [g/cm^3] Density of material. rho=density/weight/1e24*N_A.
+* DW:            [1] Global Debye-Waller factor when the 'DW' column is not available. Use 1 if included in F2.
+* focus_flip:    [1] Controls the sense of d_phi. If 0 d_phi is measured against the xz-plane. If !=0 d_phi is measured against zy-plane.
 * format:       [{}] Name of the format, or list of column indexes (see Description). N.b. no quotes!
+* geometry:    [str] Name of an Object File Format (OFF) or PLY file for complex geometry. The OFF/PLY file may be generated from XYZ coordinates using qhull/powercrust.
+* mat_format:   [{}] Format of the asorption parameter file.
+* material: [Be.txt] File where the material parameters for the absorption may be found. Format is similar to what may be found off the NIST website.
+* nb_atoms:      [1] Number of sub-unit per unit cell, that is ratio of sigma for chemical formula to sigma per unit cell.
 * p_inc:         [1] Fraction of incoherently scattered rays.
-* p_transmit:    [1] Fraction of transmitted (only attenuated) rays.
 * p_interact:    [1] Fraction of events interacting with sample, e.g. 1-p_transmit-p_inc.
-* concentric:    [1] Indicate that this component has a hollow geometry and may contain other components. It should then be duplicated after the inside part (only for box, cylinder, sphere).

+* target_index:  [1] Relative index of component to focus incoherent scattering at, e.g. next is +1
+* tth_sign:      [1] Sign of the scattering angle. If 0, the sign is chosen randomly (left and right). ONLY functional in combination with d_phi and ONLY applies to bragg lines.
 * Vc:         [AA^3] Volume of unit cell=nb atoms per cell/density of atoms.
-* DW:            [1] Global Debye-Waller factor when the 'DW' column is not available. Use 1 if included in F2.
 * weight:    [g/mol] Atomic/molecular weight of material.
-* density:  [g/cm^3] Density of material. rho=density/weight/1e24*N_A.
-* nb_atoms:      [1] Number of sub-unit per unit cell, that is ratio of sigma for chemical formula to sigma per unit cell.
