Paketti: python3-jplephem (2.21+ds-1)

Use a JPL ephemeris to predict planet positions

This package can load and use a Jet Propulsion Laboratory (JPL) ephemeris for predicting the position and velocity of a planet or other Solar System body. It currently supports binary SPK files (extension ".bsp") like those distributed by the Jet Propulsion Laboratory that are:

 * Type 2 - positions stored as Chebyshev polynomials, with velocity
   derived by computing their derivative.
 * Type 3 - positions and velocities both stored explicitly as
   Chebyshev polynomials.
 * Type 9 - a series of discrete positions and velocities, with
   separate timestamps that do not need to be equally spaced.  Currently
   there is only support for linear interpolation: for Type 9 ephemerides
   of polynomial degree 1, not of any higher degrees.

Even if an ephemeris isn't one of the above types, it is still possible to use jplephem to read its text comment and list the segments inside.
