Category EWALD (optional)

Holds information controlling the Madelung sums. The defaults are almost always adequate; for a detailed description the reader is referred to the documentation on the Madelung sums in the program in the subdirectory MAD. For `strange' structures one should check the convergence by decreasing the token TOL= (see below).
