Refraction near the horizon—an empirical approach. Part 1: terrestrial refraction of the dip: erratum

Open Access Open Access

Abstract

This erratum corrects Eq. (13a) in Appl. Opt. 55, 3104 (2016) [CrossRef]   and shows its effect on the proposed dip estimate functions Eqs. (21a)–(21d2). The differences are small, maximal up to a few percent and well within the original error limits. A new figure shows how the variability of the terrestrial refraction of the dip—as estimated with the proposed estimate functions—decreases with increasing observer heights.
