This file is the 2D far-field distribution with corresponding cavity mode. The format is

M N
x(1) y(1) Re(far-field_mode(1)) Im(far-field_mode(1)) ... Re(far-field_mode(N)) Im(far-field_mode(N))
x(2) y(2) Re(far-field_mode(1)) Im(far-field_mode(1)) ... Re(far-field_mode(N)) Im(far-field_mode(N))
...
x(M) y(M) Re(far-field_mode(1)) Im(far-field_mode(1)) ... Re(far-field_mode(N)) Im(far-field_mode(N))

, where M is the total node number and N is the total far-field mode number.
