  In this paper, we will explain a relation between [Thm. 9.5.3, Andrea
D'Agnolo and Masaki Kashiwara, Riemann-Hilbert correspondence for holonomic
D-modules, 2016] and [Thm. 6.3, Masaki Kashiwara, Riemann-Hilbert
correspondence for irregular holonomic D-modules]. For this purpose, we will
also explain a relation between enhanced ind-sheaves and enhanced subanalytic
sheaves.
