Abstract:
We present an attempt to reconstruct the complete evolutionary path
followed by cataclysmic variables (CVs), based on the observed
mass-radius relationship of their donor stars. Along the way, we
update the semi-empirical CV donor sequence presented previously by
one of us, present a comprehensive review of the connection between CV
evolution and the secondary stars in these systems, and reexamine most
of the commonly used magnetic braking (MB) recipes, finding that even
conceptually similar ones can differ greatly in both magnitude and
functional form.

Note (5): Based on the DA WD models of Holberg & Bergeron (2006,
Cat. J/AJ/132/1221) as listed at

UBVRI magnitudes are on the Johnson-Cousins systems. JHK magnitudes
have been transformed to the CIT system.

Global Notes:
Note (G1): On the Johnson-Cousins systems (Bessell 1990PASP..102.1181B 1990PASP..102.1181B).
Note that this defines two B-band filters: Bx is preferred for
calculating U-B (Ux-Bx), B is preferred for calculating other optical
colours (see Bessell (1990PASP..102.1181B 1990PASP..102.1181B) for details).
Note (G2): On the CIT system.
Note (G3): On the Johnson-Glass systems (Bessell & Brett 1988PASP..100.1134B 1988PASP..100.1134B).
Note (G4): As defined in Section 3.2 of Knigge (2006MNRAS.373..484K 2006MNRAS.373..484K):
SpT=L9 if X=1, L8 if X=2, ... L0 if X=10, M9 if X=11, ... M0 if X=20,
