List of indices of grid spaces (refers to ../grid/space) for which the source is discretely distributed. For example consider a source of 3.5 MeV alpha particles provided on a grid with two coordinates (spaces); 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.

Integrals along the markers orbit. These dimensionless expressions are of the form: (1/tau) integral (f(n_tor,m_pol,k,eq,…) dt) from time - tau to time, where tau is the transit/trapping time of the marker and f() a dimensionless function (phase factor,drift,etc) of the equilibrium (e.g. q) and perturbation (Fourier harmonics n_tor,m_pol and bounce harmonic k) along the particles orbits. In fact the integrals are taken during the last orbit of each marker at the time value of the time node below
