Notes. Best parameters determined from the fits to the average broad-band spectrum of LS 5039 performed with the XMM-Newton, Suzaku, NuSTAR, and INTEGRAL data, using the absorbed two-segment broken power-law (i.e., with one break energy) model. The multiplication factor is provided for all instruments.
