      abstract     = {The analysis and combination of data from different
                      gamma-ray instruments involves the use of collaboration
                      proprietary software and case-by-case methods. The effort of
                      defining a common data format for high-level data, namely
                      event lists and instrument response functions (IRFs), has
                      recently started for very-high-energy gamma-ray instruments,
                      driven by the upcoming Cherenkov Telescope Array (CTA). In
                      this work we implemented this prototypical data format for a
                      small set of MAGIC, VERITAS, FACT, and H.E.S.S. Crab nebula
                      observations, and we analyzed them with the open-source
                      gammapy software package. By combining data from Fermi-LAT,
                      and from four of the currently operating imaging atmospheric
                      Cherenkov telescopes, we produced a joint maximum likelihood
                      fit of the Crab nebula spectrum. Aspects of the statistical
                      errors and the evaluation of systematic uncertainty are also
                      commented upon, along with the release format of spectral
                      measurements. The results presented in this work are
                      obtained using open-access on-line assets that allow for a
                      long-term reproducibility of the results.},
