BeppoSAX observations of the BL Lac object 1E1207.9+3945
Abstract
We present the results of four X-ray observations of the BL Lac object 1E1207.9+3945 performed in 1996 with the MECS instrument onboard BeppoSAX. The source shows an unabsorbed flux in 2-10 keV range of (3.39 +/- 0.08) x 10-12 erg s-1 cm-2 with a photon spectral index of 2.12 +/- 0.06. No temporal variations during BeppoSAX observation have been detected. From the comparison with previous PSPC and EXOSAT observations, a secular variation in the 2-10 keV flux has been revealed.
