2460891.41957 (8/3/2025, 22:04)
Planet designation: TOI 1877.01 b
HJDmid: 2460891.41838 +/- 0.04783
Heliocentric correction: -0.00119
Transit depth (Mag): 0.03508 +/- 0.04312
Transit duration (Min): 188.38 +/- 189.32
Standard deviation (mmag): 8.44
Data quality index: 3
Data density (data/min): 0.79
Fitting algorithm: Original ETD
Note:20 sec binning 2x2 multicomparison stars. Due to unfavorable meteorological conditions (high cloudiness), the second half of the transit, including the egress, was not recorded. The mid-transit time was estimated using the recorded ingress and the theoretical duration from the ephemeris
