++ Objects are listed in order of increasing estimated age (using our model; see Sect. 4.4); $^{\ast}$ transient AXPs; $^{\ast\ast}$ increase in spin-down rate with $\dot{P}_{\rm new} \sim 2.3\dot{P}_{\rm old}$ for about 80 days; $^{\dag }$ very sudden spin-up during the burst with $\dot{P}_{\rm new} \sim 2 \dot{P}_{\rm old}$ for about 18 days; $^{\ddag }$ derived in our model from $B=\sqrt{3\kappa P\dot{P}}$; $^{\dag\dag }$ 80 bursts with energies ranging from $3\times 10^{34}$ to $5\times 10^{36}$.
