    Planet designation: HAT-P-12 b
    HJDmid: 2454955.77411 +/- 0.00285
    Heliocentric correction: 0.00283
    Transit depth (Mag): 0.01950 +/- 0.00340
    Transit duration (Min): 135.90 +/- 10.20
    Standard deviation (mmag): 17.1
    Data quality index: 5
    Data density (data/min): 0.59
    Fitting algorithm: Original ETD
    Note: 
    Poor quality data. Poor transparency--obvious haze from high level clouds. The moon was 75% and nearby. Lost fair amount of exposures just prior to transit due to field rotation. I had to remove about 10 data points with very large sigmas to get a fit to work. Still, I am convinced I caught the transit and the fit matches prediction remarkably well...
