        Get the transmission for each detector at the center of the given energy bins.

        If energies are not supplied will evaluate at standard science energy channels

        Parameters
        ----------
        energies : `astropy.units.Quantity`, optional
            The energies to evaluate the transmission
        attenuator : `bool`, optional
            True for attenuator in X-ray path, False for attenuator not in X-ray path

        Returns
        ---
