A Python package for historical-astronomy calculations of Sun, Moon and planets.
This package can be installed using pip install histastro. This should automatically install the
dependency packages numpy and fortranformat if they haven't been installed already. If you are installing
by hand, you have to ensure these packages are installed as well.
You will need to manually download the eight data files
VSOP87D.xxx (click on FTP), one for each of the planets,
and save them in a directory of your choice (e.g. the subdirectory data/ of your working directory). To
compute the Moon position, the file moonposMeeus.csv is needed, which can be downloaded from this page:
