Results
Rp\/Rs = 0.139 \u00b1 0.012 (expected: 0.136 \u00b1 0.0129)
O-C = -0.09 \u00b1 3.46 minutes
Quality check
Residuals STD (Standard Deviation) = 3.816 \u2030
Based on your past observations, this is better than expected (3.82 \u2030).
Diagnostics
Step 1: Transit SNR = 6.45
Transit SNR is good (strong detection of the transit)
Step 2: Rp\/Rs drift = 0.17\u03c3
The Rp\/Rs drift is good (Rp\/Rs in good agreement with the literature)
Step 3: Auto Correlation = 0.46
Step 4: Shapiro test = 0.012
The Shapiro test is good (few or no outliers in the data)<\/p>\n","protected":false},"excerpt":{"rendered":"
