The most recent RXTE Cycle 4 long-term timeline is available via anonymous FTP at heasarc.gsfc.nasa.gov in the file xte/timelines/cycle4_longterm.timeline. As RXTE scheduling is often changed to accommodate TOOs, please also consult the short-term timelines which are generated weekly. A rough rule of thumb is that any given short-term timeline will contain about half the targets from the corresponding week in the long-term timeline.
Please email xteplan if you have question about the scheduling of your observation.
If you have a question about RXTE, please send email to one of our help desks.
