## What This Project Does

====================================
 Welcome to the Skyfield project
====================================

Skyfield is a pure-Python astronomy package
that is compatible with both Python 2 and 3
and makes it easy to generate high precision research-grade
positions for planets and Earth satellites.

.. code-block:: python

   from skyfield.api import load

   planets = load('de421.bsp')
   earth, mars = planets['earth'], planets['mars']

   ts = load.timescale()
   t = ts.now()
   position = earth.at(t).observe(mars)
   ra, dec, distance = position.radec()

   print(ra)
   print(dec)
   print(distance)

The result:

::

   10h 47m 56.24s
   +09deg 03' 23.1"
   2.33251 au

Skyfield’s only binary dependency is NumPy.
Once that is available, Skyfield can usually be installed with::

    pip install skyfield

**Overall: 16/16 checks passing.**

See `ISOLATED_LAB_RESULTS/03_Result_Register.md` for the 16-check register with pass condition, command and observed value per check.

Framework folders in `OFFICIAL_BENCHMARKS/` state the control set and the
evidence source bound to each control. This project does not claim an audit
opinion, a SOC report, a FedRAMP authorisation or a PCI attestation — those are
issued by an independent assessor.
