... Because binary X-ray sources are strong emitters over a broad range of the electromagnetic spectrum, with each part of the spectrum contributing distinct and often time-variable information, attempts to understand these systems by concentrating on information from a limited wavelength range may lead to contradictory and misleading conclusions. ...
