a) Window Function for the data taken with the Lick observatory. b) Periodogram of the data showing the periods of the 3 planets previously known (υ And−b, c and d). c) Periodogram of the residuals after subtracting planets b, c and d. This periodogram shows a strong peak at a period of about 3800 days, which corresponds to planet e (see main text). d) Periodogram of the residuals after subtracting 4 orbits. This periodogram shows a strong peak (with a FAP ~0.000005) at a period of about 183 days. e) Periodogram of the residuals after subtracting 5 orbits. This periodogram shows no significant peak. FAP thresholds of 1% and 0.1% are indicated as dashed lines.
