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.
