Table 1: The characteristics of our thirteen DB + dM and two DC + dM binaries are given in this table. The uncertainties are about one subtype for the dM star and about 4000 Kelvin in WD temperature for a fixed dM spectral type. The temperatures are shown as given in Kleinman et al. (2004) for the best fit template WD. ^a See Sect. 3. ^b These objects are DC + dM binaries.
