Results
Rp/Rs = 0.1231 ± 0.0042 (expected: 0.1269 ± 0.0011)
O-C = -2.81 ± 1.87 minutes
Quality check
Residuals STD (Standard Deviation) = 4.698 ‰
Based on your past observations, this is better than expected (6.164 ‰).
Diagnostics
Step 1: Transit SNR = 14.7
Transit SNR is good (strong detection of the transit)!
Step 2: Rp/Rs drift = -0.88σ
The Rp/Rs drift is good (Rp/Rs in good agreement with the literature)!
Step 3: Auto Correlation = 0.204
The Auto Correlation is good (no systematics in the data)
Step 4: Shapiro test = 0.006
The Shapiro test is good (few or no outliers in the data)
