The estimated physical parameters of 1SWASP J130111.22+420214.0 are $M_1=1.0M_{\\odot}$, $M_2=1.63M_{\\odot}$, $R_1=0.77R_{\\odot}$, $R_2=0.91R_{\\odot}$, $L_1=0.59L_{\\odot}$, and $L_2=0.68L_{\\odot}$. While a binary model could not be fitted to the light curve of 1SWASP J231839.72+352848.2, its Fourier series representation indicates that this system could well be a rotating ellipsoidal variable.
