In our paper Barniske et al. (2008), we erroneously assigned the K-band magnitude K = 9.93 mag of the source 2MASS 17461090-2849074 from the 2MASS All-Sky Catalog of Point Sources (Cutri et al. 2003) to the nearby Wolf-Rayet type star WR 102c. This resulted in an overestimate of the stellar bolometric luminosity of WR 102c. The correct K-band magnitude of WR 102c is K = 11.6 mag (Figer et al. 1999). A comprehensive spectroscopic analysis of WR 102c is provided by Steinke et al. (2016), where the correct K-band magnitude is used. The newly derived bolometric luminosity of WR 102c is log L/L⊙ = 5.5...5.7 and the ionizing photon flux [s-1] is log (ΦLy) = 49.0...49.3.
This error does not affect any results and conclusions on the WR 102ka (the Peony star) presented in the Barniske et al. (2008) paper.
