def deprecated(since, message='', name='', alternative='', pending=False, obj_type=None):

    ''''Used to mark a function or class as deprecated.
    To mark an attribute as deprecated, use `deprecated_attribute`.
    Parameters
    since : str
    The release at which this API became deprecated.  This is
    required.
    message : str, optional
    Override the default deprecation message.  The format
    specifier ``func`` may be used for the name of the function,
    and ``alternative`` may be used in the deprecation message
    to insert the name of an alternative to the deprecated
    function. ``obj_type`` may be used to insert a friendly name
    for the type of object being deprecated.
    name : str, optional
    The name of the deprecated function or class.
if not provided
    the name is automatically determined from the passed in
    function or class, though this is useful in the case of
    renamed functions, where the new function is just assigned to
    the name of the deprecated function.  For example::
    def new_function():
    oldFunction = new_function
    alternative : str, optional
    An alternative function or class name that the user may use in
    place of the deprecated object.  The deprecation warning will
    tell the user about this alternative if provided.
    pending : bool, optional
    If True, uses a AstropyPendingDeprecationWarning instead of a
    AstropyDeprecationWarning.
    obj_type : str, optional
    The type of this object, if the automatically determined one
    needs to be overridden.'
