Remark:
mu = 0.894", ro = 163.1deg. P var. Max = 2433923.9618 +
0.054964519d*E1 - 0.00337d*sin(2pi*(0.28503379*E1 + 0.074))
(JD2433900 - 36900); since JD2436900 - see Table.
There is a periodic term in the elements given in the
Table: -0.00325*sin(2pi*(0.28503575*E2 - 0.107)). According
to [09614] for epoch 1950.0 P0 = 0.054964509,
P1 = 0.042772831, Pb = 0.1928355; dP0/dt = -87*10**(-13),
dP1/dt = -174*10**(-13), dPb/dt = 2.46*10**(-10).
P1/P0 = 0.778; 0.8m <= A <= 0.3m;
0.2p <= M-m <= 0.4p. [Fe/H] = -0.6.
