AIP Conference Proceedings, Volume 1223, pp. 239-244 (2010).Blazars are a small fraction of all extragalactic sources but, unlike other objects, they are strong emitters across the entire electromagnetic spectrum. In this study we have conducted a detailed investigation of the broad-band spectral properties of the gamma-ray selected blazars of the Fermi LAT Bright AGN Sample (LBAS). By combiningthe accurately estimated Fermi gamma-ray spectra with Swift, radio, NIR-Optical and hard-X/gamma-ray data, collected within three months of the LBAS data taking period, we were able to assemble high-quality and quasi-simultaneous Spectral Energy Distributions (SED) for 48 LBAS blazars. Here we show the procedure for the multi wavelength analysis.galactic nucleiastronomical telescopessky surveysX-ray sources (astronomical)spectrumgamma-rays PACS Keywords Galactic haloX- and gamma-ray telescopes and instrumentationAstronomical catalogs atlases sky surveys databases retrieval systems archives etc.X-ray sourcesX-ray burstsComposition energy spectra and interactionsgamma-ray sourcesgamma-ray burstsconference paper10.1063/1.3395991http://adsabs.harvard.edu/abs/2010AIPC.1223..239G2010AIPC.1223..239G
