The paper describes the different methods, used in the MAGIC experiment, to unfold experimental energy distributions of cosmic ray particles (γ-rays). Questions and problems related to the unfolding are discussed. Various procedures are proposed which can help to make the unfolding robust and reliable. The different methods and procedures are implemented in the MAGIC software and are used in most of the analyses. © 2007 Elsevier B.V. All rights reserved.
