****************************************************** PR # 42124 We propose to observe MCG-5-23-16 with ASCA and XTE to monitor the shape and variability of the continuum and reprocessed flux. Our goal is to measure the iron fluorescence line and Compton reflection component simultaneously on short and long timescales to determine their origins. This science can only be done with joint ASCA and XTE observations. MCG-5-23-16 is an excellent candidate because it is bright, variable, and its iron line shows both a narrow and broad component. This suggests that we will almost certainly be investigating the accretion disk and the molecular torus. ******************************************************
