Abstract
AGRAWAL et al.1 present an interesting observation of the variable X-ray source Cygnus XR–1 at energies above 20 keV. This communication points out that their observations may be consistently interpreted in terms of the eclipsing binary model for the source that was originally outlined in an article by myself2 (article 1).
