Analysis of the system V736 And. Left: Light curves of pairs A and B from the TESS satellite. Right: ETV analysis of both pairs, with all the data collected for the star from various surveys. Larger symbols represent data taken with a higher weight because of their better-quality data (e.g. TESS). The filled dots are the primary eclipses; the open circles are for the secondary ones. The solid red curve for pair A stands for the classical light travel time effect fit, while for pair B such a fit with an opposite shape is plotted as a dashed blue line (obviously not fitting the data).
