Notes:   Confirmed binary, WD+dM4.5 (2MASS colors consistent with dM1-5), a = 1.105″ (2007AJ....134...26H and references therein). 1978ApJ...226..411E and 2000AJ....119..241L classify WD0116-231 as DA+dM (the latter may just be repeating the classification from the former); however, 1979ApJ...227..232B list WD0116-231 in their table of composite spectra stars (dK or dM plus a blue star) as sd0.
