Summary: We correct the definitions and descriptions of the integral structures by the author [A study of mirror symmetry through log mixed Hodge theory. Contemporary Mathematics 608, 285–311 (2014; Zbl 1314.14018)]. The previous flat basis by the author [loc. cit.] is characterized by the Frobenius solutions and is integral in the first approximation by mean of the graded quotients of monodromy filtration, but it is not integral in the strict sense.
In this article, we use $$\widehat\Gamma$$-integral structure of by H. Iritani [Ann. Inst. Fourier 61, No. 7, 2909–2958 (2011; Zbl 1300.14055)] for A-model. Using this precise version, we study open mirror symmetry for quintic threefolds through log mixed Hodge theory, especially the recent result on Néron models for admissible normal functions with non-torsion extensions in the joint work [Proc. Japan Acad., Ser. A 90, No. 1, 6–10 (2014; Zbl 1303.14022)] with K. Kato and C. Nakayama. We understand asymptotic conditions as values in the fiber over a base point on the boundary of $$S^{\log}$$.
