Left, bottom: GX 17+2 rates normalized to the weighted average (10.9 $\pm$ 0.9 c/s); in the first 3 ScW the source was outside the ISGRI FOV. Right: NRAO 530 rates; upper limits are at $3\sigma$ . In the top of the figure, the distance of the source from the ISGRI FOV centre is shown in every ScW. All the lightcurves are in the 20-40 keV energy band.

Radio data from NED and Bower et al. (1997). Reference value of optical observations from Hewitt & Burbidge (1993); historical maximum from Pollock et al. (1979), Webb et al. (1988). X-rays: ROSAT (Comastri et al. 1997), Einstein (Marscher & Broderick 1981), HEAO-1 (Marscher & Broderick 1981). $\gamma$ -rays: CGRO/EGRET (Hartman et al. 1999). Blue cross: IBIS/ISGRI, present work.
