Notes. The points N1...N4 are for the non-flashing 0.212 M_⊙ WD model and the points F1...F9 are for the 0.221 M_⊙ flashing WD model.

^(a)

Age relative to the previous point along the track.

^(b)

Cumulated age relative to the first point on the track (since the time of Roche-lobe detachment).

^(c)

Total amount of hydrogen remaining in the envelope of the (proto)-He WD.
