| + | Finally, some of the sources can be also altered after they are set, e.g. to change the source profile. | ||
| + | This is the case of LTSF and TSF (in z direction) where we can multiply the plane wave entering the computational domain by a Gaussian to get a slightly diverging Gaussian beam. | ||
