Skyfield (astro/py-skyfield) is a Python library for astronomical computations.
|
|
It depends on various data files to accurately compute moon phases, planet
|
|
positions, etc. Several issues are raised by these data files:
|
|
|
|
- If they're not found in the path of the Loader, they're downloaded at
|
|
runtime. Depending on the archive you're requesting, some files might be very
|
|
large, causing a long delay (directly related to your network bandwidth). In
|
|
the case of a web server app, you'd cause a timeout on client's end.
|
|
|
|
- They come mainly from 2 sources: NASA's JPL, and the IERS. If one of them is
|
|
temporarily unavailable, you couldn't perform any computation.
|
|
|
|
- In some countries, or behind some filtering proxies, some hosts may be
|
|
blocked.
|
|
|
|
- These files have an expiration date (in a more or less distant future). As a
|
|
consequence, even if the files are already downloaded in the right path, at
|
|
each runtime you could possibly have to download one or more files before
|
|
making any computation using them.
|
|
|
|
This package provides at least the most common of these assets.
