The standard data reduction pipeline of the program uses aperture photometry to construct the light curves. We alternatively apply the difference imaging method for the most complete field in the survey and carry out a quantitative comparison between the photometric precision of both methods for objects with J<18. We also report an implementation on the box-fitting detection algorithm, which performs a trapezoid-fit to the folded light curve.
