The common profile constants remain uniform under the four unit phases used in complex polarization. The proof uses their actual weighted Schwartz seminorm definition, without taking a maximum over the finite packet family.

    Source documentation

    The precise common profile constant is subadditive under polarization, with the expected modulus of the scalar coefficient.

    Source documentation

    Two profiles with the same bound have polarization profiles bounded by twice that constant, uniformly for every unit complex phase.
