Remark:
P var. Max = 2416415.360 + 0.51127069d*E
(JD2413000 - 19000) [00001]; Max = 2426161.4375 +
0.51124948D*E (JD2426000 - 38000) [00323];
since JD2438000 - see Table.
Blazhko effect, height of Max varies: 10.6m - 10.9m,
Max (Delta(m)) = 2430904.3 + 116.654d*N + 0.01034d*N**2;
Min (Delta(m)) - Max (Delta(m)) = 59.3d [03419].
[Fe/H] = -1.69; Delta(S) = 10.0.
