Note 2. Those parameters that are not directly determined from non-LTE model atmosphere analysis - for example wind parameters derived from present day nebular properties - are given in italics. Due to the extreme mass loss rate for  Car a degeneracy is present for the stellar radius and temperature (Hillier et al. 2001). References used in the construction of this table are ^a Clark et al. (2003a) and this study; ^b Drissen et al. (2001); ^c Petit et al. (2005); ^d Petit et al. (2006); ^e Koenigsberger et al. (1998) ^f Humphreys et al. (1999); ^g Smith et al. (2003); ^h Smith (2005); ⁱ Smith (2008); ^j Hillier et al. (2001); ^k Smith & Hartigan (2006); ^l Najarro (2001). Volume filling factors, f, range from 0.1 (HD 5980 and  Car), through 0.3 (NGC 2363-V1) to 0.5 (P Cygni). Time averaged mass loss rates for  Car and P Cygni derived from nebular masses are absolute (i.e. f = 1). Finally, note that the values of  presented for NGC 2363-V1 in 1997 & 1999 are from Drissen et al. (2001), while R_*, , and  are from the updated models presented by Petit et al. (2005).
