      \caption{\label{tab:hkin}H$\alpha$ Moreton wave kinematics derived with the "visual" method. $v_{1}$ 
and $v_{l}$ are the measured first and last velocities, $v_{0~{\rm est}}$ the 
velocity obtained from the polynomial fit of~$r(t)$ at the estimated starting 
time, $\bar v$ the mean velocity derived from a linear fit, $r_{\rm min}$ and~$r_{\rm max}$ the minimum and maximum distances of the wavefronts, $\bar a$ the 
average deceleration derived from the polynomial fits, and~$\delta$ is the exponent of the power-law fits. The last four rows give the mean 
values and standard deviations~$\sigma$ of the parameters obtained by the 
"visual" and the "profile method", respectively. Values in brackets are 
inaccurate and are not used for deriving the mean values. Decelerations are 
given in~m~s$^{-2}$, velocities in km~s$^{-1}$, and distances in~Mm~(10$^3$~km).}
