Possible content for type: NBI or reaction names (see distsource_types in the Documentation website under Conventions/Enumerated_datatypes); the field name should either be taken from nbi(*)%nbi_unit(*)%name, or describe the populations involved in the reaction, e.g. fast-thermal; the field index should separate different sources generated from a single injector or reaction.

For example consider a source of 3.5 MeV alpha particles provided on a grid with two coordinates; rho_tor and energy. To specify that the source is given at energies exactly equal to 3.5 MeV, let discret have length 1 and set discrete=(1)=2 since energy is dimension number 2. The source is then proportional to delta( 1 - energy / 3.5MeV ), where delta is the Direct delta distribution. Discrete dimensions can only be used when the grid is rectangular.
