Abstract:
We present a spectral catalog for blazars based on the BeppoSAX
archive. The sample includes 44 High-energy peaked BL Lacs (HBLs),
14 Low-energy peaked BL Lacs (LBLs), and 28 Flat Spectrum Radio
Quasars (FSRQs). A total of 168 LECS, MECS, and PDS spectra were
analyzed, corresponding to observations taken in the period 1996-2002.
The 0.1-50keV continuum of LBLs and FSRQs is generally fitted by a
single power law with Galactic column density.
Description:
Spectral parameters for 168 BeppoSAX observations of 86 blazars are
presented.
For each blazars observation data, count rates, flux, spectral
parameters (intrinsic absorption, photon index, energy break, and
reduced chi-squared) derived from the analysis are given.
