(A–D) TF gated photon coincidence counting $g_{TF}^{(2)}(t_1,{\omega }_1;t_2,{\omega }_2)$ [S62] vs. ${\omega }_1$ and ${\omega }_2$ using gating parameters ${\mathrm{\Gamma }}_{\omega 1}={\mathrm{\Gamma }}_{\omega 2}=2{\lambda }_0$, ${\mathrm{\Gamma }}_{T1}={\mathrm{\Gamma }}_{T2}=2.5{\lambda }_0$ for $t_1=T-20\tau$, $t_2=T+20\tau$ (A); $t_1=T$, $t_2=T-20\tau$ (B); $t_1=T+20\tau$, $t_2=T-20\tau$ (C); and $t_1=T+20\tau$, $t_2=T$ (D). (E–H) Same but for PS gating $g_{PS}^{(2)}(t_1,{\omega }_1;t_2,{\omega }_2)$ [S61] using gated bandwidth ${\mathrm{\Gamma }}_{ps1}={\mathrm{\Gamma }}_{ps2}=2{\lambda }_0$ cm⁻¹.
