v8 v9 23 23 Once it is done, the GUI '''get_field''' pops up again. Keep '1D plot' in the '''[!FieldOptions]''' table and select 'UHisto' or 'Vhisto' in the '''[Ordinate]''' one. The '''[Coordinates]''' should change according to the input in the '''[Ordinate]''' ('U' if 'UHisto' is selected, same for 'V' and 'VHisto'). Select '''[OK]'''. 24 24 25 A curve, close to a Gaussian, (gathering all the vectors from the difference between all the analytic and synthetic files of the series) appears in '''uvmat'''. On the right hand corner a table shows all the parameters of this curve. In the scroll bar '''[Field/get_field]''' it is possible to get back to the GUI '''get_field''' and change the '''[Ordinate]'''. You can also '''[Export]''' the curve '''[in new figure]''' or '''[on existing axis]'''.25 A curve, close to a Gaussian, (gathering all the vectors from the difference between all the analytic and synthetic files of the series) appears in '''uvmat'''.
