Abstract: Since 2002, the number of detected blazars at γ-ray energies above 100 GeV has more than doubled. A synoptic study of these objects therefore might reveal important collective characteristics. I study all currently known high-frequency peaked BL Lac-type objects for which photon energy spectra at E > 100 GeV have been inferred. The intrinsic energy spectra of the sources are reconstructed using a state-of-the-art model for the extragalactic background light. Then, the properties of the observed emission are compared and correlated among each other, with X-ray data, and with the individual estimated black hole masses. In addition, I consider temporal properties of the found VHE γ-ray flux. Key findings concern the connection of observed photon flux and estimated black hole mass as well as the correlation between the spectral slope and the luminosity. The latter correlation is also studied for sources for which individual distinct flux states have been observed. As a specific application, the synoptic study allows to constrain the redshift of PG 1553+113, a TeV blazar whose distance is unknown to date.
