\caption{Spectral lag measurements for \textit{INTEGRAL} GRBs. The columns refer to (from left to right): GRB; supergalactic longitude (SGL) and latitude (SGB); burst interval used in
spectral lag determination relative to trigger time and  as marked on time profiles in
the Appendix; spectral lags measured between Channel~2 (50$-$100~keV) and Channel~1 (25$-$50~keV), $\tau_{2,1}$, Channels~2 and~3 combined (50$-$300~keV) and Channel~1 (25$-$50~keV), $\tau_{2+3,1}$ and Channel~3 (100$-$300~keV) and Channel~1 (25$-$50~keV), $\tau_{3,1}$.}\label{table:speclags}
