* Four ''[[wp:Correlation_coefficient|correlation coefficients]]'': one for each of the four possible combinations of the two polarizing beam splitter angles. These measure the interrelatedness of light detection events on the two sides of the experiment. |

* A ''[[wp:CHSH_inequality|CHSH contrast]]'', which is derived from the correlation coefficients. |
* A ''[[wp:CHSH_inequality|CHSH contrast]]'', which is derived from the correlation coefficients. |

The estimated CHSH contrast is what we are really interested in, because what we intend to show is that it contradicts what many physicists believe. |

Quantum mechanics predicts a CHSH contrast of approximately <math>2\sqrt{2}\approx{2.828427}</math>. The ''[[Simulated optics experiment/Simulator]]'' simulation will be shown (by our analysis) to have a CHSH contrast very close to that. Note that our simulation does not employ any quantum mechanics, but instead simulates light [[wp:Classical_physics|"classically"]]. Also our simulation clearly involves only causation that in each instance takes a finite amount of forward-moving time. That is, there is no "[[wp:Action_at_a_distance|instantaneous action at a distance]]". |
