Table 6
Tabulated PLR differences due to the finite width of the IS, calculated as blue edge minus red edge, and due to metallicity differences as solar minus LMC metallicity for Wesenheit indices WVI and WH,VI as shown in Fig. 15.

Notes. For a fixed period, Cepheids near the blue edge are brighter than those near the red edge, and solar metallicity Cepheids brighter than LMC metallicity Cepheids, hence the tabulated magnitude differences are negative.
