Notes:νorb is the orbital frequency and corresponding period found earlier spectroscopically (Cowley et al. 1975); νpr− is the frequency corresponding to the nodal precession period; ν− is the frequency of the negative superhumps; ν+ is the frequency of the positive superhumps. Here, a is amplitude of the sinusoid that best fits the folded light curve.
