release note : version 0.7.3-b

automatic grid sizing

Te option automatic_grid_sizing includes now the automatic determination of n_x, n_y. The rule is, after calculating automatic cut_x and cut_y, to take n_x = 4.*cut_x/sigma_x and n_y = 4.*cut_y/sigma_y.

Remark : If the beams are generated bt program (load_beam = 0) the user must give in the data the beam size and emittance parameters. But, in the case of load_beam = 1, these data are not mandatory if the option automatic_grid_sizing is activated. In this last case, if sigma_x, sigma_y, sigma_z are (directly or indirectly) given the program uses these data for all purposes except the computation of cut_x, cut_y, cut_z. If they are not given it uses calculated values from loaded beam.

bug fixing

The output file gives now the actual values of cut_x, cut_y, cut_z
