We present a method for analysis of multiwavelength data from blazars. By assuming the radio through X-ray flux is nonthermal synchrotron emitted by isotropically-distributed electrons in the randomly oriented magnetic field of a relativistic jet, one can obtain the electron spectrum. This spectrum is then used to deduce the Compton spectrum as a function of a small set of parameters. The full Compton cross-section is used, which is accurate in the Thomson through Klein-Nishina regimes. Photoabsorption by interactions with internal jet radiation and the extragalactic background light (EBL) is included. The exact form of the EBL is not well-known, and the results can vary greatly depending on the EBL used. We find that a one zone synchrotron self-Compton model is unable to explain the very high energy gamma-rays from the 2006 flare detected in the X-ray selected BL Lac PKS 2155-304.
