How to use scattnlay

Compile Code:

Compilation options

• make source - Create source package (python library)
• make install - Install on local system (python library)
• make buildrpm - Generate a rpm package (python library)
• make builddeb - Generate a deb package (python library)
• make standalone - Create a standalone program
• make clean - Delete temporal files

Use:

1. Python library

   • Use scattnlay directly

     from scattnlay import scattnlay
     ...
     x = ...
     m = ...
     terms, Qext, Qsca, Qabs, Qbk, Qpr, g, Albedo, S1, S2 = scattnlay(x, m)
     ...
     

     • Execute some of the test scripts (located in the folder 'tests/python') Example: bash ./test01.py

2. Standalone program

   • Execute scattnlay directly Usage:

     scattnlay -l Layers x1 m1.r m1.i [x2 m2.r m2.i ...] [-c comment]
     

     • Execute some of the test scripts (located in the folder 'tests/shell') Example: bash ./test01.sh > test01.csv

3. C++ library

   try {
     MultiLayerMie multi_layer_mie;
     multi_layer_mie.SetLayersSize(x);
     multi_layer_mie.SetLayersIndex(m);
   
     multi_layer_mie.RunMieCalculation();
   
     *Qsca = multi_layer_mie.GetQsca();
     *Qabs = multi_layer_mie.GetQabs();
   } catch(const std::invalid_argument& ia) {
     // Will catch if  multi_layer_mie fails or other errors.
     std::cerr << "Invalid argument: " << ia.what() << std::endl;
     throw std::invalid_argument(ia);
     return -1;
   }
