    HJDmid: 2459957.45492 +/- 0.00042
    Heliocentric correction: -0.00432
    Transit depth (Mag): 0.02180 +/- 0.00060
    Transit duration (Min): 101.80 +/- 1.60
    Standard deviation (mmag): 0.4
    Data quality index: 1
    Data density (data/min): 0.23
    Fitting algorithm: Original ETD
    Note: 
    240 second exposure through Rc filter.  GPS time control.  Partial due to clouds just prior to egress.  NOTE ETD HJD conversion appears different to alternative conversion sources (E.g. https://doncarona.tamu.edu/apps/jd/) or AstroImageJ.  Converted time is expected to be 459957.46491(HJD).  ETD Tc(HJD) is 0.01d early.
