  We present precise Raviart-Thomas interpolation error estimates on
anisotropic meshes. The novel aspect of our theory is the introduction of a new
geometric parameter of simplices. It is possible to obtain new anisotropic
Raviart-Thoma error estimates using the parameter. We also include corrections
to an error in "General theory of interpolation error estimates on anisotropic
meshes" (Japan Journal of Industrial and Applied Mathematics, 38 (2021)
163-191), in which Theorem 3 was incorrect.
