This package consists of three parts:

  • calcmysky utility that does the precomputation of the atmosphere model to enable rendering.

  • libShowMySky library that lets the applications render the atmosphere model.

  • ShowMySky preview GUI that makes it possible to preview the rendering of the atmosphere model and examine its properties.

SEP consists of a C library with no dependencies outside the standard library, and a Python module that wraps the C library in a Pythonic API. The Python wrapper operates on NumPy arrays with NumPy as its only dependency.
