      Remark:         
    [Fe/H] = -1.2. P var. Max = 2417201.241 + 0.4665878*E -
    0.000107d*10**(-6)*E**2 (JD2414000 - 35000) [02550];
    Max = 2438562.796 + 0.466570d*E (JD2434000 - 39800);
    Max = 2440445.789 + 0.466497d*E (JD2439800 - 41000)
    [06237]; Max = 2441453.3856 + 0.4664731d*E
    (JD2441000 - 42500) [07424]; Max = 2443028.641 +
    0.466438d*E (JD2442500 - 43800) [09101]; Max =
    2444142.650 + 0.466649d*E (JD2443800 - 44200)
    [09102]; since JD2444100 - see Table.
    Besides that the star has a strongly
    expressed Blazhko effect; the period of Blazhko effect
    varies, too [07424, 07425]. 0.13P <= M - m <= 0.22P;
    0.90m <= A(B) <= 1.70m, 0.70m <= A(B) <= 1.30m;
    -0.05P < O - C < +0.05;
    Max A = 2417025.5 + 57.401d*E (JD2417000 - 38500);
    Max A = 2438881.7 + 58.387d*E (since JD2438500).[09103].
    After JD2444000
    Blazhko effect period probably decreased to 56.3d [09102].
