class BeamTypes(Enum):
    """
    Enumeration of beam types used in WODEN.

    This class allows us to label the WODEN primary beam models with a unique
    name/value, but as it's an enum each label only takes 8 bytes of memory, so we can
    stack loads of them into an array. We can also do numpy operations on them like np.where.

    Attributes:
        NO_BEAM (int): No beam type.
        GAUSS_BEAM (int): Gaussian beam type.
        FEE_BEAM (int): FEE beam type.
        ANALY_DIPOLE (int): Analytical dipole beam type.
        FEE_BEAM_INTERP (int): Interpolated FEE beam type.
        MWA_ANALY (int): MWA analytical beam type.
