Energy-Norm A Posteriori Error Estimates for Singularly Perturbed Reaction-Diffusion Problems on Angonal domains. Linear finite elements are considered on anisotropic triangulations. The error constants are independent of the diameters and the aspect ratios of mesh elements and of the small perturbation parameter. The case of the Dirichlet boundary conditions was considered in the recent article
