1 2012arXiv1208.3591A Transit-like features in the light curve occur every 204.2 days, lasting 1.26 days (5 orbital periods) with multiple fading events.
2 Otero, Sebastian Alberto Also eclipses with elements BJD 2454997.743313 + 204.2163 x E and approximate eclipse duration 1.26 d. This may be a low mass eclipsing binary orbited by a transiting planet or a triple system made up of a very low mass eclipsing binary orbiting a K-type dwarf. Amplitude given is for the deepest crossing during the third body passage. Amplitude of the low binary eclipses are 0.013 and 0.011 mag.
3 Jansen, R J-K= 0.578. Not resolved by SuperWASP due to low amplitude.
