CLEANING UP PHOTOMETRIC TIME SERIES Cleaning up photometric time series

Filtering out systematic effects from photometric time series has become a major issue ever since the launch of the massive search for transiting extrasolar planets in the early years of this century. Due to the imperfection of the data acquisition and various environmental effects, systematics are always present in the acquired data, independently of the size and the base of the telescope. Therefore, effective systematics filtering is vital for all projects aimed at faint signal search.

In the talk we review the basic methodologies, the past and present successes, including the wide-field ground- and space-based surveys. In particular, we discuss the recent developments in the data analysis related to the 2-Wheel mission of the Kepler satellite.
