What the beam's attributes say. beam is off when it is missing, off or false; a bare attribute, selected or on switches it on for the chosen satellite. The strength is from 0 to 1 (0.6 when left out), the elevation from 0 to 80 degrees (25), the cells from 0 to 91 (none) and the cell size in kilometres (0 for the fit).
