Goniospectrometric space curve for coatings with special effect pigments: erratum

Open Access Open Access

Abstract

In the original publication [Appl. Opt. 55, 122 (2016) [CrossRef]  ], Eq. 5(c) was wrong. The correction for it is given here.

Equation 5(c) of the original publication [1] was wrong; the correct form is presented here as Eq. (1):

μz=cosφas.

Consequently, the z axis of figures showing the xDNA curves was also affected. Figures 2(b), 4(a), 6(b), 8(a), 9(b), 9(d), 10(b), 12(a), 13(b), 13(d), 14(b), and 14(d) from [1] undergo negligible changes; thus they are not presented here. More changes were needed for Fig. 3(b); the corrected form is presented here as Fig. 1. The correct z values are smaller, which is more evident when the surface coverage is lower (smaller C value). Figures 7 and 11 from [1] show differences analogous to Fig. 3(b) from [1]; therefore they are not presented here.

The corrected version of Fig. 5(a) from [1] is shown here as Fig. 2. The most noticeable effects are smaller z values, which become important at high values of mean flake tilt angle. Figures 8(b) and 12(b) from [1] show the same differences as Fig. 5(a) from [1]; therefore they are not presented here.

Although there was an error in Eq. 5(c) of the original publication [1], all the conclusions stay valid. The corrected version with all the affected figures is available on request at marta.k.gunde@ki.si.
