Abstract: Since the last large sample of Galactic WC stars had been analyzed in the middle of the 1990s, significant improvements have been achieved in the simulation of stellar-wind spectra. We have (partly re-) analyzed all available Galactic WC stars with the current generation of stellar atmosphere models computed with the Potsdam Wolf-Rayet (PoWR) code. In contrast to previous results, the obtained stellar parameters now show a close correlation with the WC subtype. The stellar temperatures form a sequence from 45 kK (WC9 subtype) to about 120 kK (WC4). For those stars with known distance, we also derived luminosities using flux-calibrated spectra and photometry.
