How to use scattnlay

Table of contents:

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:
./test01.py
  1. 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:
./test01.sh > test01.csv
  1. 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;
    }
