pro hvězdu CU CVn

    According to BVRI photometry performed by K. Hoňková and J. Juryšek, the light curve has amplitude 0,05 mag in I band and almost twice larger amplitude in B band. Together with slightly asymetric shape of light curve, it proves that CU CVn is not an eclipsing binary, but the pulsating one (probably delta Scuti).

    The light curve looks much more like RR Lyr than EW. There is clearly visible asymetry and maximas are too sharp for EW star.
