An analysis of the infrared light curve of XN Musc in quiet stage has been carried out using photometric data of Remillard et al. (1992) in the framework of the standard X-ray binary model, a Roche model star and an accretion disk around a relativistic object. A statistical verification of the selected model for the observation data is made. The orbital inclination is determined. Taking into account the information about the mass of the optical K0V-K4V star (Mv = 0.7-0.8 solar mass) and the mass function fv(M) = 3.1 solar masses, obtained by Remillard et al. (1992), the parameters of the system are determined: q = Mx/Mv = 12-21, i = 39-43 deg, and Mx = 9-16 solar masses.
