The peak radial velocity of object 1, <math>K</math>, depends on the orbital inclination <math>i</math> (an inclination of 0° corresponds to an orbit seen face-on, an inclination of 90° corresponds to an orbit seen edge-on). For a circular orbit ([[orbital eccentricity]] = 0) it is given by<ref name="tauris">{{cite book |last1=Tauris |first1=T.M. |last2=van den Heuvel |first2=E.P.J. |author2-link=Ed van den Heuvel |editor1-last=Lewin |editor1-first=Walter |editor1-link=Walter Lewin |editor2-last=van der Klis |editor2-first=Michiel |editor2-link=Michiel van der Klis |title=Compact stellar X-ray sources |publisher=Cambridge, UK: [[Cambridge University Press]] |date=2006 |pages=623–665 |chapter=Chapter 16: Formation and evolution of compact stellar X-ray sources |chapterurl=httphttps://arxiv.org/abs/astro-ph/0303456 |isbn=978-0-521-82659-4 |doi=10.2277/0521826594 |lastauthoramp=y}}</ref>
