Table 3: Summary of the results for all the X-ray observations on LS 5039 performed by instruments with imaging capabilities. The unabsorbed fluxes in the energy range 0.3-10 keV, photon indices, and $N_{\rm H}$ (with wabs model) values are given. BeppoSAX flux errors are the flux dispersion accounting for the count rate changes by a factor of two during the observation and neglecting photon index variations. ASCA flux errors are assumed to be 10% of the flux. The given 2005 XMM-Newton $N_{\rm H}$ values are computed with the wabs model for comparison with 2003 values. For more details, see M05 (2003 XMM-Newton data), R03 ( BeppoSAX data), and Yamaoka, K., private communication ( ASCA data).
