Fig. 3
ROSAT count rate corresponding to an unabsorbed flux of 10-11 erg cm-2 s-1 versus the Galactic hydrogen column density NH for the three values of the X-ray photon spectral index Γx = 1 (blue), 2 (red), and 3 (green). Plus signs indicate the values derived with WebPIMMS, and solid curves represent polynomial fits through them. Open circles correspond to the NH values of our LPBLs.
