The OBC Bad Fraction is the fraction of the observation of the star during which one or more of the common column, defective pixel, multiple star, or ionizing radiation status flags are set on the star.
The log color scale is fixed across these plots and at the time of the creation of these plots (2012-Aug) year 2012 does not have data for the full year.
