TL;DR: The Compton Gamma-Ray Observatory (COMPTEL) as discussed by the authors is a gamma-ray line spectrometer with an angular resolution between 1° and 2° within a large field of view of about 1 steradian.

L. Kuiper,W. Hermsen,G. Cusumano,Roland Diehl,V. Schönfelder,Andrew W. Strong,K. Bennett,Mark L. McConnell +7 more
TL;DR: In this paper, the authors presented the time-averaged characteristics of the Crab pulsar in the 0.75-30 MeV energy window using data from the imaging Compton Telescope COMPTEL aboard the Compton Gamma-Ray Observatory (CGRO) collected over its 9-year mission.
The Soft Gamma-Ray Spectral Variability of Cygnus X-1

TL;DR: In this paper, the authors used observations of Cygnus X-1 from the Compton Gamma-Ray Observatory (CGRO) and BeppoSAX to study the variation in the MeV gamma-ray emission between the hard and soft spectral states, using spectra that cover the energy range 20 keV up to 10 MeV.

TL;DR: The first complete all-sky survey in the energy range 0.75 to 30 MeV was provided by NASA's Compton Gamma-Ray Observatory (COMPTEL) as discussed by the authors, which contains firm and marginal detections of continuum and line emitting sources and presents upper limits for various types of objects.
Deducing Electron Properties From Hard X-Ray Observations
Eduard P. Kontar,John C. Brown,A. G. Emslie,A. G. Emslie,Wojtek Hajdas,Gordon D. Holman,G. J. Hurford,Jana Kašparová,Procheta Mallik,Anna Maria Massone,Mark L. McConnell,Michele Piana,Marco Prato,E. J. Schmahl,E. Suarez-Garcia,E. Suarez-Garcia +15 more
TL;DR: In this paper, the authors discuss the role and the observational evidence of several radiation processes: free-free electron ion, freefree electron-electron, free-bound electron-ion bremsstrahlung, photoelectric absorption and Compton back-scatter (albedo), using both spectroscopic and imaging techniques.
