Parameters
################################################################################
.. note:: All parameters are optional for the Equal Area Cylindrical projection.
.. include:: ../options/lat_ts.rst
.. include:: ../options/lon_0.rst
.. include:: ../options/ellps.rst
.. include:: ../options/R.rst
.. include:: ../options/k_0.rst
.. include:: ../options/x_0.rst
.. include:: ../options/y_0.rst
.. note::
``lat_ts`` and ``k_0`` are mutually exclusive. If ``lat_ts``
is specified, it is equivalent to setting ``k_0`` to
:math:`\frac{\cos \phi_{ts}}{\sqrt{1 - e^2 \sin^2 \phi_{ts}}}`
