  Title: COMPLETING THE GLOBULAR CLUSTER PROJECT: A COORDINATED ASCA/XTE OBSERVATION OF X0513-401 (NGC 1851)


Abstract:
 We propose to complete our project to observe bright globular cluster LMXBs with an
 ASCA AO-4 observation of X0513-401 (NGC 1851). X0513-401 is the final source in the
 program; although C time was awarded in ASCA AO-3, it was not included in the final
 timeline. The project aims to relate the abundances in the sources with those of the
 surrounding clusters, study the continuum and burst emission, and search for lines
 and edges; for X0513-401 we will also search for low-level orbital modulations.
 X0513-401 is important for this study as it is located in a metal-poor cluster. In
 addition, we have obtained XTE AO-1 time which can be scheduled simultaneously,
 enabling us to correlate the fast timing activity of the source with its spectral state.
