 | Comparison between the results on $\ad$ obtained from the 2006 data set and the previous results from COMPASS. |
 | Comparison between the combined COMPASS results on $\ad$ {and the} world data (CLAS \cite{CLAS}, HERMES \cite{Hermes}, SMC \cite{smc}, E155 \cite{e155d} and E143 \cite{e143}). {All data points are shown at their measured $Q^2$ values.} |
 | Results on $\ad$ from the combined COMPASS data in bins of $x$ and $Q^2$. |
 | Comparison between SMC \cite{smc} and combined COMPASS results on $\gd$. The systematic uncertainty is illustrated by the bands at the bottom. {All data points are shown at their measured $Q^2$ values.} |
 | World data on the spin-dependent structure function $\gd$ as a function of $Q^2$ for various values of $x$ with the combined COMPASS data as filled circles. The lines represent the $Q^2$ dependence for each value of $x$ as determined from the updated NLO QCD fit {to the world data}. The dashed parts represent the region with $W^2 < 10\,(\GeV/c^2)^2$. |
 | Values of $\int_{x_{\rm min}}^1 \gd/(1-1.5\omega_D) dx$ as a function of $x_{\rm min}$. The open circle at $x = 0.7$ is obtained from the fit. The arrow on the left side shows the value for the full range, $0 \leq x \leq 1$. |
