  • 摘要:In our paper Barniske et al. (2008), we erroneously as- signed the K-band magnitude K = 9.93mag of the source 2MASS17461090-2849074 from the 2MASS All-Sky Catalog of Point Sources (Cutri et al. 2003) to the nearby Wolf-Rayet type star WR102c. This resulted in an overestimate of the stel- lar bolometricluminosityof WR102c.The correct K-bandmag- nitude of WR102c is K = 11.6mag (Figer et al. 1999). A comprehensive spectroscopic analysis of WR102c is provided by Steinke et al. (2016), where the correct K-band magnitude is used. The newly derived bolometric luminosity of WR102c is logL/L ? = 5.5...5.7 and the ionizing photon flux [s −1 ] is log(Φ Ly ) = 49.0...49.3.
