Navigation:  Scatterers > General scatterers

This type of scatterers simply imports the required spectral data to compute K, S and W(Θ) from external data files. The external files must be created by other programs.

For practical reasons, the external data must be provided in a form that the volume fraction can be changed afterwards. In fact, the volume fraction of the scatterers is the only parameter of general scatterers.

 

General scatterer windows look like this:

 

 

Scattering data are imported using the Import menu command. The following file formats for data input are supported:

•RT file fomat (RT = Radiation Transfer), described below

 

After setting the volume fraction in the corresponding input box you have to use the Update menu command to compute K, S and W(Θ). K and S are displayed in the window (blue and red curve). At present, the angle dependence cannot be viewed in general scatterer objects but has to be inspected with the external program View_rt delivered with SPRAY.
