Determined transits
  • 2460978.54291 (10/30/2025, 01:01)
    Planet designation: TOI-7403 .01
    HJDmid: 2460978.54673 +/- 0.01721
    Heliocentric correction: 0.00382
    Transit depth (Mag): 0.02430 +/- 0.00550
    Transit duration (Min): 128.45 +/- 56.95
    Standard deviation (mmag): 7.44
    Data quality index: 3
    Data density (data/min): 1.77
    Fitting algorithm: Original ETD  
    Note: 
    30 sec binning 2x2 multicomparison stars. Due to unfavorable meteorological conditions (high cloudiness), the beginning of the transit was not recorded. The mid-transit time was estimated using the recorded egress and the theoretical duration from the ephemeris
