SchoutenCC is a reserved word in xTras. It is used to generate the name of the cosmological Schouten curvature tensor associated to a connection acting on a tangent bundle.
The cosmological Schouten tensor is the usual Schouten tensor plus a term proportional to the cosmological constant, such that it vanishes solutions to the equation of motion.
The name of the cosmological Schouten tensor is "SchoutenCC + name of covariant derivative".
The cosmological Schouten tensor has three indices; the first is a label index for the value of the cosmological constant, the last two are the usual tangent bundle indices.
