CAFOS spectra of known (red) and new (black) cool DC WDs. The spectral types of known objects, CA009 = WD 0019+423, CA069 = WD 0344+014, CA454 = WD 2215+368, CA212 = WD 1033+714, CA287 = LSPM J1341+0500, with typical errors of less than about 0.1 subtypes are taken from the following references: (1) = Limoges et al. (2015), (7) = Putney (1997), (8) = Greenstein (1984), (11) = Sion et al. (2014), (14) = Holberg et al. (2008), (28) = Subasavage et al. (2007), (42) = Giammichele et al. (2012), and (52) = Sayres et al. (2012). The spectra are roughly sorted by the slope of their continuum. A terrestrial absorption band is marked.
