P var, Delta(m) var. According to [G.Henriksson, Uppsala Rep N26, 1983.], P = 1.490795d + 1.22d*10**(-6)*(JD - 2443600)/365.25d. Cyclic P variations: P alpha = 1178.5d; Pt = 2655d. Delta(m) varies with the period P alpha; P4 = 1063.5d may be traced in the variations of Vr. 0.06m <= Delta(m) <= 0.36m.
