Orbital I-band differential light curves and the respective fits for the data segments.

<p>Orbital I-band differential light curves and the respective fits for the data segments. The dashed line indicates the maximum brightness of the system in the orbital phase 0.25 during all the observations. All the brightness curves are normalized in relation to this maximum brightness. The flux contribution from the disk, gainer and donor are documented versus the orbital phase, along with pictures showing the system appearance at different strings.</p>
