The asteroseismic diagram initially described by Christensen-Dalsgaard (1988) plots the average small separations between modes of degree =0,2 against the average large separations . Here we show that even if the only modes available are of degree =0,1 the separations and can be combined to give the internal phase shift difference 1-0 and hence a diagnostic similar to, but different from, d02. We give an example of the =0,1 asteroseismic diagram for the mean value d01 plotted against for a range of stellar masses in different stages of evolution.
