 with $E_0 = \langle \psi | O_1 | \psi \rangle$. The spectrum is returned as a spectrum object. Please note that fluorescence yield is the expectation value of an Hermitian operator. The returned spectrum is thus completely real. Possible options are: with $E_0 = \langle \psi | O_1 | \psi \rangle$. The spectrum is returned as a spectrum object. Please note that fluorescence yield is the expectation value of an Hermitian operator. The returned spectrum is thus completely real. Possible options are:
