Abstract:
In this paper, a sample of 451 blazars (193 flat spectrum radio
quasars (FSRQs), 258 BL Lacertae objects) with corresponding X-ray and
Fermi γ-ray data is compiled to investigate the correlation both
between the X-ray spectral index and the γ-ray spectral index
and between the spectral index and the luminosity, and to compare the
spectral indexes αX, αγ, αXγ, and
αγXγ for different subclasses. We also
investigated the correlation between the X-ray and the γ-ray
luminosity.

Note on table4.dat: For comparison, we also obtained a sample of 289 blazars
based on the 1FGL catalog (Abdo et al. 2010, Cat. J/ApJS/188/405) and the
blazar sample (Massaro et al. 2009, Cat. J/A+A/495/691, the Roma BZCAT,
Multi-frequency Catalogue of Blazars) to redo the calculations and analysis.
