Fig. 4

Left: pixel frame for EPIC 206028594, also known as NGC 7300; the colour goes from white (low flux) to blue (high flux). Indicated are the masks defined by K2P2, the Harvard pipeline (Vanderburg & Johnson 2014), and the photometric analysis (PA) component of the Kepler science processing pipeline (Bryson et al. 2010). We also show (with red masks) the two other targets identified by K2P2 under the constraint of a minimum pixel mask of 8 pixels. Right: image of NGC 7300 from the Southern Sky Atlas (SERC), with colours and orientation modified to match in appearance the K2 data.
