\caption{Observationally inferred pulsar data. Note that in
\citet{elgkmw2005} no value for $\beta$ is quoted. Also, we infer
$P_3$ from their values of $P_2$ and using the relation for the
drift rate $D (^\circ/P_1) = P_2(^\circ)/P_3(P_1)$, which is a
good approximation for this system, as it is nearly aligned.
Positive and negative values are obtained due to the definition of
drift rate. } \label{table:info}
