The idea of distributing JPL ephemerides as Python packages proved to be impractical (they were much too large for the Python Package Index to easily store and distribute), and it forced `jplephem` users get their ephemerides from a different source than mainline astronomers, who use SPICE files. This package's documentation now recommends avoiding this old code, and using the features now build directly into the `SPK` class instead.

The position is returned as a NumPy array ``[x y z]``. The barycentric dynamical time `tdb` argument should be a float. If there are many dates you want computed, then make `tdb` an array, which is more efficient than calling this method multiple times; the return value will be a two-dimensional array giving a row of values for each coordinate. For extra precision, the time can be split into two floats; a popular choice is to use `tdb` for the integer or half-integer date, and `tdb2` to hold the remaining fraction.

The return value is a tuple that bundles together the coefficients and other Chebyshev intermediate values that are needed for the computation of either the position or velocity. The bundle can then be passed to either `position_from_bundle()` or `velocity_from_bundle()` to finish the computation. See the package-level documentation for details; most users will simply call `position()` or `position_and_velocity()` instead. The barycentric dynamical time `tdb` argument should be a float.
