    <description>
      This database table was created for the purpose of providing a comprehensive, accurate, and easily accessible tracking of Rossi X-Ray Timing Explorer (RXTE) pointed observations. It does not list observations made during slews: those are listed in the &amp;lt;a href="/W3Browse/xte/xteslew.html"&amp;gt;XTESLEW&amp;lt;/a&amp;gt; database table. The XTEMASTER table includes both observations that have already completed and those still scheduled to be done. The XTEMASTER table is regenerated automatically on a quasi-regular basis whenever the RXTE Science Operations Facility (SOF) updates their short-term or long-term schedules and transfers the new version(s) to the HEASARC. At that time, it will also incorporate all the latest information on which targets have been observed (using the daily RXTE ObsCats at &amp;lt;a href="https://heasarc.gsfc.nasa.gov/FTP/xte/timelines/obscat/"&amp;gt;https://heasarc.gsfc.nasa.gov/FTP/xte/timelines/obscat/&amp;lt;/a&amp;gt;) and which observations have been archived in the public RXTE Data Archive at &amp;lt;a href="https://heasarc.gsfc.nasa.gov/FTP/xte/data/archive/"&amp;gt;https://heasarc.gsfc.nasa.gov/FTP/xte/data/archive/&amp;lt;/a&amp;gt;. This is a service provided by NASA HEASARC .
