K2SC: Flexible systematics correction and detrending of K2 light curves using Gaussian Process regression

30 Mar 2016 Suzanne Aigrain Hannu Parviainen Benjamin Pope

We present K2SC (K2 Systematics Correction), a Python pipeline to model instrumental systematics and astrophysical variability in light curves from the K2 mission. K2SC uses Gaussian process regression to model position-dependent systematics and time-dependent variability simultaneously, enabling the user to remove both (e.g., for transit searches) or to remove systematics while preserving variability (for variability studies)...
