Typical plot of our signal detection algorithm for object 1.40_14711, a K dwarf being orbited by a hot Jupiter candidate. Low resolution spectroscopy confirms the stellar type determined through SED fitting (see also Sect. 3). Shown at the top are period (days), transit duration q (in units of phase), transit v shape (0 corresponds to a box, 1 to a V), transit light drop, S/N and number of transits/number of points in the transits. The binned data points are shown in red. A green line shows the best-fitting 2-level system, including the v-shape adjustment.
