of $a\leftrightarrow b$;

3.  in the case of $a_- = 0$, $a_{1,+}$ and $b_{1,+,-}$ should satisfy ${a_1} = {t_{13}}{a_ + }{e^{i{\delta _{CP}}}}$, ${b_ - } = b_1/{t_{12}c_{13}}$ and ${b_ + } =  - {t_{13}}{b_1}{e^{ - i{\delta _{CP}}}}$;

4.  in the case of $b_- = 0$, $a_{1,+,-}$ and $b_{1,+}$ should satisfy relations in the case of $a_- = 0$ with the interchange of $a\leftrightarrow b$;

5.  in the cases of $a_+ = 0$ and $b_+ = 0$, no simple linear expressions arise.

and, for IH, we find that

1.  in the case of ${{a_ + } = - {t_{13}}{a_1}{e^{ - i{\delta _{CP}}}}}$, $a_-$ and $b_{1,+,-}$ should satisfy ${b_ + } =  - {t_{13}}{b_1}{e^{ - i{\delta _{CP}}}}$;

2.  in the case of $a_1 = 0$, $a_{-,+}$ and $b_{1,+,-}$ should satisfy ${a_ + } = 0$ and ${b_ + } =  - {t_{13}}{b_1}{e^{ - i{\delta _{CP}}}}$;

3.  in the case of $b_1 = 0$, $a_{1,+,-}$ and $b_{+,-}$ should satisfy relations in the case of $a_1 = 0$ with the interchange of $a\leftrightarrow b$;

4.  the case of $a_+ = 0$ ($b_+ = 0$) is identical to the case 2 (the case 3);

5.  the case of $a_- = 0$ ($b_- = 0$) is
