Combining ray data.
It is sometimes necessary to combine together the initial conditions of two or more different sets of rays eg two beams (defined using the beam option) that have different energies.
The only way that this can be done at present is via manual editing. Each of the sets of rays can be set up with the data-builder and then the ray output file can be edited to extract the initial conditions of the rays (which are either in a suitable format for re-use as input data or can be put in a suitable form). The different sets can then be added together and the data file can be run in the 'manual editing' mode.
