Notice: The RXTE Archive will be offline Memorial Day weekend (May 28 -
June 1) due to hardware problems. This includes all processed, realtime
and ASM data served from the HEASARC. Data served by SOF computers
should not be affected.
This page contains information on XTE TOO observations. Both results
on observations that have already been performed and plans for upcoming
TOO observations. The amount of information that can be provided on future
observations will depend on how rapidly the TOO observation must be performed.
Remote Observation Service for Public TOOs
Anyone who is interested in monitoring public TOO observations in real time can use
our Remote Observation Service. Detailed information is given in
RXTE Remote Observing Interface page.
Information of up coming PUBLIC TOO observations is available in
All TOO List page.
Request of TOO
In order to request a TOO observation an RFO
(Request for Observation)
must be submitted. Messages regarding scheduling
of regular XTE observations should be sent to
and general questions regarding XTE should go to
Please note that there are two categories of TOO observations: (i)
Observations for which an accepted proposal exists. In this case data rights
are the same as for any accepted proposal. (ii) Observations for which
there is no accepted proposal. For the second category the data are
public immediately. After an observation
of this type has undergone standard processing
(which includes conversion to FITS format) and archiving, the data
will be available by standard means. Information on how to obtain
public TOO data is available from the XTE GOF.
Already performed TOO Observations
Currently Planned TOO Observations
- GRO J1744-28 - The PCA modes we presently plan to use for this
monitoring campaign are:
- We are currently planning a monitoring campaign for GRO 1744-28. If
you wish to suggest observing strategies or modes please submit an RFO
(Request for Observations).
Please note that all data collected will become public domain even if
we follow your recommendations for observations strategies or modes!
