Spectral energy distribution of the total emission from the Crab pulsar and pulsar wind nebula as measured by COMPTEL in 30 bins covering the energy band 0.78–30 MeV. Filled red dots correspond to results obtained with ctools, and open blue dots correspond to results obtained by van der Meulen et al. (1998) using COMPASS. The shaded regions correspond to the 1σ uncertainty bands of the fitted exponentially cut-off power-law models.
