Photometric Detrending Algorithm

PDT (Photometric DeTrending Algorithm Using Machine Learning) aims to remove systematic trends in the light curves. For details about the algorithm, see [Kim et al. 2009](http://adsabs.harvard.edu/abs/2009MNRAS.397..558K). In brief, PDT finds clusters of light curves that are highly correlated using machine learning, construct one master trend per cluster and detrend an individual light curve using the constructed master trends by minimizing residuals while constraining coefficients to be positive.
