CAFOS spectra of known (red) and new (black) cool DA WDs. The spectral types of known objects, CA024 = WD 0101+048, CA203 = WD 1019+637, CA011 = WD 0025+054, CA480 = WD 2322+137, with typical errors of less than about 0.1 subtypes are taken from the following references: (1) = Limoges et al. (2015), (11) = Sion et al. (2014), (16) = Drilling et al. (2013), and (36) = Gianninas et al. (2011). The spectra are roughly sorted by the slope of their continuum. The locations of the Balmer lines and of a terrestrial absorption band are marked on the bottom.
