****************************************************** PR # 140 The 5.57 hr LMXRB X1822-371 is an eclipsing binary. The eclipse is partial, indicating the X-ray source is hidden behind an accretion disk coronae. The ASCA observation will study the spectrum as a function of binary phase.A large fluorescent iron K line is expected because the X-ray emission is scattered to the observer via the corona. ******************************************************
