   PR # 41055
   This is the fifth and the last in the series of proposals to sample
   over the entire 162-d precession phases of SS 433 in four years.
   Since PV until AO-3 observations we have covered the precession phase
   range of 0.98 - 0.65. In AO-4, we proposed to make observations at
   around phase 0.8 to complete the uniform coverage over the entire
   precession phase. Furthermore, we plan to have simultanous
   observations with XTE to obtain the wide-band X-ray spectrum from 0.5
   keV up to 100 keV for the first time. The binary phase -0.15, 0.0 and
   +0.15 will be sampled, and the high-temperature region close to the
   source of the jet will be studied.
