Computes the signal-to-noise ratio (SNR) of an exoplanet transit using transit depth, RMS scatter, and the number of in-transit and out-of-transit points (all values assumed in ppt where applicable). * Methodology
| Potential SNR (if OOT → ∞) | — |
| Effective points (Neff) | — |
| Depth / RMS | — |
Note: this assumes independent (white) noise. Time-correlated (“red”) noise can make the true significance lower.
