Table 1: Data of observations.
Table 2: Results for power law fits to the data of orbit 171-1 in limited energy bands, assuming galactic absorption ( $N_{\rm H} = 1.66\times 10^{20}$ cm^-2).
Table 3: Characteristics of the variability of the light curves.
Table 4: Results for broken power law fits for Mrk 421in the energy band 1.5-12.0 keV, assuming Galactic absorption.
Table 5: Cross-correlation analysis results. $CCF_{\rm max}$ is the maximum CCF value, and $k_{\rm max}$ the lag at which this maximum appears (i.e. the "delay"). Both results were estimated using a model fitting procedure (see text for details).
