... The end-of-mission performance depends on the scanning law. A more accurate standard error can be computed by: 1) Multiplying the mean value by a geometrical scaling factor (g), different for each of the five parameters (see figure and table) 2) Taking into account the individual number of transits ...

Activity and rotation of Kepler-17
... The solar-type star analysed here, Kepler-17, is a prominent candidate to study stellar magnetic activity, as its light curve shows rotational modulations caused by the presence of starspots, with an amplitude variation of 4% (Figure 1). The Sun, for comparison, presents a modulation of only about 0 ...
