Table 1: Best-fit parameters of the joint RXTE+ INTEGRAL spectrum of SS433 observed in March 24-27, 2004. The model is bremsstrahlung emission and a Gaussian emission line (from the XSPEC package). The energy of the emission line was a free parameter. The physical nature of the line is not discussed in the present paper.
