Description

We have collected a large amount of multifrequency data for objects in the Metsahovi Radio Observatory BL Lacertae sample and computed their spectral energy distributions (SED) in the log{nu}-log{nu}F representation. This is the first time the SEDs of BL Lacs have been studied with a sample of over 300 objects. The synchrotron components of the SEDs were fitted with a parabolic function to determine the synchrotron peak frequency, {nu}_peak_. We checked the dependence between luminosities at several frequency bands and synchrotron peak frequency to test the blazar sequence scenario, which states that the source luminosity depends on the location of the synchrotron peak. We also calculated broad band spectral indices and plotted them against each other and {nu}_peak_.
