in the VarTools light curve analysis program [@hartman08] was used for detection of sharp periodic signals. We obtained the period and [*False Alarm Probability*]{} of peaks which are significant at a level greater than 3$\sigma$. We detect significant peaks in the power spectra at periods between 2–5 days, the most significant being at 4.39days. We improved the light elements of the system using the Wilson-Devinney code [@Wil03]. The light and radial velocity curve of the system is phased with the following ephemeris and period:

$$T_{\mathrm{minI}} = 2453189.668(58) + 4^d.3942894(48)  \times E.$$

The orbital period is very close to that estimated by @ote. The radial velocities and photometric observations were phased using these light elements.

Radial velocity analysis {#sec:rv}
------------------------

Radial velocities (RV) of the components were derived with a standard cross correlation algorithm, IRAF’s tool FXCOR. We used the wavelength interval 4500 – 5000 Å, which is rich in metallic lines. As cross correlation template, we chose the nearby primary target $\iota$Psc (F7V) of similar spectral type and we used, for reference, as the RV standard. The radial velocities of the components were derived by fitting two Gaussian curves with the FXCOR function and presented in Table1.
